Question: Atlanta (CNN) -- It was somewhere in the middle of Six Flags' Goliath roller coaster that my eye started to short-circuit, nearly going black. The towering roller coaster pressed my fellow riders and me deep into our seats as we rounded a set of sharp curves. Many find the ride thrilling; for me it was unnerving. I spent much of my time in line for the next ride of the day, the Batman roller coaster, reading about the potential for roller coaster deaths and accidents. This was Friday in Georgia, the same day a woman died after falling from her seat on a Six Flags coaster in Texas. Pecking through roller coaster news on my phone that day, before the death in Texas had been reported, I learned, among other things, that it was reported that a 45-year-old died after passing out and having an apparent heart attack on Goliath, the ride that made my eye briefly malfunction. I get that this seems paranoid, and I knew reading this information while waiting in line for a roller coaster was an unnecessary form of self-torture. But I couldn't help it. There's something about a roller coaster death that is uniquely terrifying in a screenplay kind of way. It's summer fun gone horribly wrong. I think this is partly why so many are shocked and saddened by the death of Rosy Esparza, who fell, according to a witness who spoke with CNN affiliate WFAA, from the Texas Giant roller coaster at Six Flags in Arlington, Texas. The exact cause remains unknown, but authorities say there was no sign of "foul play or criminality." Six Flags said in a statement that safety is paramount. "Since the safety of our guests and employees is our number one priority, the ride has been closed pending further investigation," the park said. A park spokeswoman did not immediately respond to requests for comment on its safety inspection policies and the calls for federal oversight. Still, it's a reluctant thrill seeker's greatest fear. It's almost impossible to imagine how terrifying the experience would be -- and how family members and fellow riders could process such an accident. After Esparza's death, Sen. Ed Markey, the Democrat from Massachusetts who recently took the seat vacated by John Kerry, has reportedly renewed his call for federal oversight of roller coaster inspection. "No federal agency has legal authority to enforce safety standards," NBC wrote in a post about the safety issues. "And Texas is one of at least 17 states that have no agency responsible for inspecting amusement park rides, according to NBC News' survey of state codes in all 50 states." Markey wants a federal agency to oversee safety enforcement. The Consumer Product Safety Commission regulates mobile amusement park rides, like those found at fairs, but does not have jurisdiction over "fixed" rides like those at Six Flags, said Scott Wolfson, a spokesman for the federal agency. The difference makes little sense, and Markey isn't alone in his call for more oversight. Tracy Mehan, from the Center for Injury Research and Policy at Nationwide Children's Hospital in Columbus, Ohio, said that relatively little is known about the prevalence of roller coaster injuries and deaths because the federal government doesn't enforce safety inspections and investigations. A patchwork of state laws govern the process, she said. Would-be roller coaster regulators have been criticized as needlessly scaring people about the dangers of roller coasters. And it's true that the statistics aren't quite as terrifying as the rides. As the National Review put it this year, "Americans are 5,000 times more likely to be legally executed by their own government than to die on a roller coaster." The writer, Charles C.W. Cooke, puts the odds of roller coaster death at 1 in 1.5 billion in a given year, compared with a 1 in 10 million chance of being killed "because the aircraft he is traveling on falls apart." But that framing is misleading, given how little is known about national roller coaster injuries. One of the best sources of information comes from a Center for Injury and Policy Research study of child injuries in the United States. After looking at injuries that were treated in hospitals from 1990 to 2010, the group found that a child is hospitalized from an injury related to an amusement park, carnival, fair or arcade-type ride once every three days in the summer, Mehan said. These are serious injuries: fractures, neck injuries and traumatic brain injuries. Including less serious injuries like bruises and sprains, about 4,440 child injuries are reported to hospitals each year on the rides, including those at fairs and other attractions, she said. The rate is 20 injuries per day during the summer months. "We would really like to see a national database or a national system put in place so we can get a picture of what's happening," she said. The group was unable to compile info on deaths, for example. Regardless of the stats, however, it's the joy-gone-wrong factor that makes roller coaster deaths particularly horrifying. Are those fears slightly irrational and disproportionate? Maybe. But safety seems far from assured these days. Improvements, of course, must be weighed against deadlier public safety concerns. More should be done, for instance, to prevent road-traffic deaths, which kill about 1.3 million people globally each year. Many of those deaths could be prevented with simple changes to traffic laws and other rules, according to a fascinating report from Bloomberg Philanthropies (PDF); and self-driving cars could lead to greater reductions, still. But the existence of more-pressing and deadlier threats does not justify lax oversight of amusement park rides that are meant to entertain. Roller coaster fans should support a review of safety requirements. Otherwise, at the very least, they risk having a joyous experience soured by fear.

Question: Washington (CNN) -- New details emerged of what the White House knew about the Internal Revenue Service targeting of conservative groups, with spokesman Jay Carney disclosing Chief of Staff Denis McDonough was among the top officials made aware of the matter late last month. In a new timeline provided by Carney to reporters on Monday, General Counsel Kathryn Ruemmler learned on April 24 of a pending Treasury inspector general's report on how IRS staff used criteria targeting conservative groups in assessing eligibility for tax-exempt status. According to Carney, Ruemmler told McDonough as well as other Treasury officials about the pending report. It was the first time the White House acknowledged that McDonough was aware of the report before it became public in early May. IRS: By the numbers . In addition, Carney made clear that the information Ruemmler received on April 24 included details of improper acts by IRS officials. At the same time, Carney emphasized that the information was preliminary and could have changed before the inspector general released his final report on May 14. Carney insisted no one -- including Ruemmler and McDonough -- told President Barack Obama anything about the inspector general's pending report before media reports about it began appearing on May 10. "We knew the subject of the investigation and we knew the nature of some of the potential findings, but we did not have a copy of the draft report," Carney said. "We did not know the details, the scope, or the motivation surrounding the misconduct and we did not know who was responsible. Most importantly, the report was not final and still very much subject to change." Opinion: What happened to Obama's promise? However, the new information on Monday continued a perception of a White House on the defensive over the issue, one of at least three controversies dogging Obama as his second term reaches the four-month mark. The Senate Finance Committee will hold the second congressional hearing on the matter Tuesday, after the House Ways and Means Committee grilled the outgoing acting commissioner of the IRS last Friday. On Monday, the Senate panel's Democratic chairman and ranking Republican sent a letter to the IRS official, Steven Miller, seeking an exhaustive list of information about the case. Another hearing is set for Wednesday by a third panel -- the House Oversight Committee. Some Republicans are calling for a special investigation into the IRS matter, in which tax officers assessing applications for tax-exempt status used key words such as "tea party" in determining levels of scrutiny. CNN Poll: Likability helps Obama survive brutal week . Separately on Monday, a Northern California tea party group filed the first lawsuit against the U.S. government stemming from the IRS targeting. "The IRS and its agents singled out groups like NorCal Tea Party Patriots for intensive and intrusive scrutiny, probing their members' associates, speech, activities and beliefs," according to the suit filed in Cincinnati. "NorCal and its members suffered years of delay and expense while awaiting the exemption and spending valuable time and money answering the IRS' questions. The result was a muffling and muzzling of free expression" the lawsuit claimed. The group alleged violations under the Privacy Act as well as violations of its constitutional rights guaranteeing free expression and equal protection under the law. Opinion: We're pointing a gun at our democracy . Carney offered the new timeline in response to the first question at his daily media briefing, when a reporter noted "confusion" over what Ruemmler was told about the inspector general report in late April. He noted the report found no outside intervention in the IRS targeting of what he called "inappropriate scrutinizing of conservative groups" seeking tax-exempt status, and that no one in the White House intervened in the inspector general's review or "did anything that could be see as intervening." In addition, Carney said, the misconduct had stopped in May 2012, almost a year before Ruemmler or anyone else at the White House were told of it by anyone at Treasury. At the same time, Carney disclosed that White House and Treasury officials discussed the pending inspector general's report in the weeks before its formal release, even though he said no one told Obama about it. The White House first was notified of the upcoming report, known as an audit, on April 16, he said, calling that a routine notification also provided to Congress. Ruemmler was told about it eight days later and she informed McDonough and others about it shortly thereafter, Carney said. "Ruemmler was informed that the inspector general for tax administration was completing a report about line IRS employees improperly scrutinizing what are known 501(c)(4) organizations by using words such as 'tea party' and 'patriot'," he said. In particular, Carney said that "at no time did anyone on the White House staff intervene with the IRS inspector general audit." "There were communications between the White House Counsel's office and White House Chief of Staff's office with Treasury Office of General Counsel and Treasury's Chief of Staff office to understand the anticipated timing of the release of the report and potential findings by the" inspector general, he said, but added that Ruemmler acted properly in not informing the president. IRS official denies intentional political targeting, lying to Congress . "The cardinal rule, as I said, is you do not intervene in an independent investigation and you do not do anything that would be, that would give such an appearance particularly when the final conclusions, as was the case here, have not been reached," Carney said. "That is the doctrine we followed and the bottom line is, and this isn't just the most important fact, it is what we have said from the beginning - neither the White House nor Treasury intervened in the inspector general's audit." Last week, Miller blamed a huge increase in workload, rather than deliberate targeting, for "foolish mistakes" in the political discrimination cited by the inspector general's report. He told the House Ways and Means Committee that the IRS division handling requests for tax exempt status was overwhelmed by a surge that followed the Supreme Court's 2010 Citizens United decision. "I think that what happened here was that foolish mistakes were made by people who were trying to be more efficient in their workload selection," Miller said, calling the practices described in the inspector general's report as "intolerable" and a "mistake," but "not an act of partisanship." He apologized for what he later called "horrible customer service," but he also stubbornly rejected any accusation that it amounted to politicizing the work of the IRS. However, Republicans noted the increased requests for tax exempt status didn't kick in until 2011, months after the targeting began, according to the inspector general's report. Rep. Dave Camp, chairman of the Republican-led panel, and other GOP members sought to depict the controversy as indicative of government gone wild, with the IRS abusing conservative groups and other political foes of the administration. Democrats on the committee also expressed outrage at the targeting of conservative groups seeking tax-exempt status, but they pointed out that the top IRS official at the time was appointed by Republican President George W. Bush, not Obama. Opinion: IRS scandal is about donors, not tax . They also noted that the inspector general's report stated there was no evidence of any political motivation for what happened, or influence from outside the IRS. The Treasury Department oversees the quasi-independent IRS. Some Republicans are trying to find a link between the Obama administration and the IRS targeting. According to the inspector general's report, the IRS developed and followed a faulty policy to determine whether the applicants were engaged in political activities, which would disqualify the groups from receiving tax-exempt status. The controversial move began in early 2010 and continued for more than 18 months, the report said, declaring that "the IRS used inappropriate criteria that identified for review Tea Party and other organizations applying for tax-exempt status based upon their names or policy positions instead of indications of potential political campaign intervention." Among the criteria used by IRS officials to flag applications was a "Be On the Look Out" list, which was discontinued in 2012, the report said. Conservative groups complain their requests were delayed for months or even years through the targeting that sought to prevent ineligible political groups from getting tax exempt status. Miller testified Friday that determining the political nature of groups was one of the hardest tasks of IRS officers tasked with assessing requests for tax exempt status. The investigation by the Treasury inspector general for tax administration was initiated after congressional complaints began to surface in the media in 2012 that the IRS was targeting conservative groups and holding up applications. In a written response included in the report, the IRS commissioner of the Tax Exempt and Government Entities Division said there was no criminal behavior behind the actions of the agents, but rather inefficient management. Obama called the inspector general's findings outrageous and forced Miller's resignation. In addition, the commissioner of the IRS' Tax Exempt and Government Entities Division also announced his retirement Thursday. Joseph Grant will leave in June, according to an internal IRS memo provided to CNN. Miller also is scheduled to exit then. Obama has appointed Danny Werfel, a White House budget office official who has served in both Democratic and Republican administrations, to succeed Miller through the end of the fiscal year on September 30.

Question: London (CNN) -- Four current and former employees of Britain's Sun newspaper were arrested by authorities investigating claims of inappropriate payments to police, News Corp. and police said Saturday. Police searched the men's homes as well as the East London offices of News International, the News Corp. subsidiary that publishes the Sun and other U.K. newspapers, London's Metropolitan Police Service said. A 29-year-old police officer was also arrested Saturday at the central London police station where he works, police said, on suspicion of corruption, misconduct in a public office and conspiracy in relation to both offenses. He works for the force's Territorial Policing command. Three of the men were arrested at their homes -- two of them, aged 49 and 57, in the county of Essex, and one aged 48 in London. A fourth, aged 42, was arrested at an east London police station. By late Saturday, police said that all five men were subsequently released after posting bail. The current and past newspaper employees were all set to "return pending further inquiries" in April or May, according to the Scotland Yard statement. Earlier, they'd been questioned on suspicion of corruption, aiding and abetting misconduct in a public office, and conspiracy in relation to those offenses. The operation "relates to suspected payments to police officers and is not about seeking journalists to reveal confidential sources in relation to information that has been obtained legitimately," an earlier police statement said. News Corp. said it is cooperating with the search of its News International offices. Police said the operation was the result of information provided to police by News Corporation's Management and Standards Committee (MSC), which was set up to look into conduct at News International, a subsidiary of News Corp. The News Corp. statement said the company had "made a commitment last summer that unacceptable news gathering practices by individuals in the past would not be repeated." The committee was asked "to proactively co-operate with law enforcement and other authorities if potentially relevant information arose at those titles. As a result of that review, which is ongoing, the MSC provided information to the Elveden investigation which led to today's arrests." The Sun, which is Britain's best-selling tabloid newspaper, was the sister paper of News International's now-defunct Sunday title, the News of the World. A spokeswoman for News International earlier declined to comment on the search of its offices. The investigation into alleged corruption, known as Operation Elveden, is being run in conjunction with an inquiry into phone hacking prompted by allegations of wrongdoing at News of the World. The best-selling News of the World tabloid was shuttered in July amid outrage over claims that its staff hacked the voicemail of a missing 13-year-old girl who turned out to have been murdered. James Murdoch, chief executive of News International and the son of media mogul Rupert Murdoch, has insisted that the practice of phone hacking was not widespread. News Group Newspapers, a subsidiary of News International that was the publisher of News of the World, agreed to payouts in the High Court totaling hundreds of thousands of dollars earlier this month over phone hacking claims. Among those who read statements in court were Labour Party lawmaker Chris Bryant, former Deputy Prime Minister John Prescott, actor Jude Law, the actor's ex-wife Sadie Frost, and high-profile rugby player Gavin Henson. News International said the company "made no admission as part of these settlements that directors or senior employees knew about the wrongdoing by NGN or sought to conceal it. However, for the purpose of reaching these settlements only, NGN agreed that the damages to be paid to claimants should be assessed as if this was the case." Both James and Rupert Murdoch, as well as senior executives at News International, have testified before British lawmakers examining allegations of wrongdoing. A public inquiry has also been set up to look at claims of widespread misconduct by the British media. Representatives of a range of news outlets have appeared before it. There have been 13 arrests in connection with Operation Elveden and 17 in relation to Operation Weeting, the phone hacking inquiry, the Metropolitan Police confirmed. Three people have been arrested in connection with both investigations. Operation Elveden is overseen by the British police watchdog, the Independent Police Complaints Commission.
