Question: What new powers did the employer of Melvin Purvis now have?

full_context: Document 1: Dillinger (1973 film): Retired FBI Agent Clarence Hurt, one of the agents involved in the final shootout with Dillinger, was the film's technical advisor. The film includes documentary imagery and film footage from the era. It includes a verbal renouncing of gangster films written by FBI chief J. Edgar Hoover: he was scheduled to read it for the film, but died before it started production. Hoover's text is read at the film's close by voice actor Paul Frees.
Document 2: Federal Bureau of Investigation: Despite its domestic focus, the FBI also maintains a significant international footprint, operating 60 Legal Attache (LEGAT) offices and 15 sub-offices in U.S. embassies and consulates across the globe. These overseas offices exist primarily for the purpose of coordination with foreign security services and do not usually conduct unilateral operations in the host countries. The FBI can and does at times carry out secret activities overseas, just as the CIA has a limited domestic function; these activities generally require coordination across government agencies.
Document 3: War on Terror: The USA PATRIOT Act of October 2001 dramatically reduces restrictions on law enforcement agencies' ability to search telephone, e-mail communications, medical, financial, and other records; eases restrictions on foreign intelligence gathering within the United States; expands the Secretary of the Treasury's authority to regulate financial transactions, particularly those involving foreign individuals and entities; and broadens the discretion of law enforcement and immigration authorities in detaining and deporting immigrants suspected of terrorism-related acts. The act also expanded the definition of terrorism to include domestic terrorism, thus enlarging the number of activities to which the USA PATRIOT Act's expanded law enforcement powers could be applied. A new Terrorist Finance Tracking Program monitored the movements of terrorists' financial resources (discontinued after being revealed by The New York Times). Global telecommunication usage, including those with no links to terrorism, is being collected and monitored through the NSA electronic surveillance program. The Patriot Act is still in effect.
Document 4: Federal Bureau of Investigation: From the end of the 1980s to the early 1990s, the FBI reassigned more than 300 agents from foreign counter-intelligence duties to violent crime, and made violent crime the sixth national priority. With reduced cuts to other well-established departments, and because terrorism was no longer considered a threat after the end of the Cold War, the FBI assisted local and state police forces in tracking fugitives who had crossed state lines, which is a federal offense. The FBI Laboratory helped develop DNA testing, continuing its pioneering role in identification that began with its fingerprinting system in 1924.
Document 5: Federal Bureau of Investigation: The FBI has been frequently depicted in popular media since the 1930s. The bureau has participated to varying degrees, which has ranged from direct involvement in the creative process of film or TV series development, to providing consultation on operations and closed cases. A few of the notable portrayals of the FBI on television are the 1993-2002 series The X-Files, which concerned investigations into paranormal phenomena by five fictional Special Agents and the fictional Counter Terrorist Unit (CTU) agency in the TV drama 24, which is patterned after the FBI Counterterrorism Division. The 1991 movie Point Break is based on the true story of an undercover FBI agent who infiltrated a gang of bank robbers. The 1997 movie Donnie Brasco is based on the true story of undercover FBI agent Joseph D. Pistone infiltrating the Mafia.
Document 6: Federal Bureau of Investigation: In 2005, fugitive Puerto Rican Nationalist leader Filiberto Ojeda Ríos died in a gun battle with FBI agents in 2005 in what some charged was an assassination.[citation needed] Puerto Rico Governor Aníbal Acevedo Vilá criticized the FBI assault as "improper" and "highly irregular" and demanded to know why his government was not informed of it. The FBI refused to release information beyond the official press release, citing security and agent privacy issues. The Puerto Rico Justice Department filed suit in federal court against the FBI and the US Attorney General, demanding information crucial to the Commonwealth's own investigation of the incident. The case was dismissed by the U.S Supreme Court. Ojeda Rios' funeral was attended by a long list of dignitaries, including the highest authority of the Roman Catholic Church in Puerto Rico, Archbishop Roberto Octavio González Nieves, ex-Governor Rafael Hernández Colón, and numerous other personalities.
Document 7: Federal Bureau of Investigation: Hoover began using wiretapping in the 1920s during Prohibition to arrest bootleggers. In the 1927 case Olmstead v. United States, in which a bootlegger was caught through telephone tapping, the United States Supreme Court ruled that FBI wiretaps did not violate the Fourth Amendment as unlawful search and seizure, as long as the FBI did not break into a person's home to complete the tapping. After Prohibition's repeal, Congress passed the Communications Act of 1934, which outlawed non-consensual phone tapping, but allowed bugging. In the 1939 case Nardone v. United States, the court ruled that due to the 1934 law, evidence the FBI obtained by phone tapping was inadmissible in court. After the 1967 case Katz v. United States overturned the 1927 case that had allowed bugging, Congress passed the Omnibus Crime Control Act, allowing public authorities to tap telephones during investigations as long as they obtain a warrant beforehand.
Document 8: Federal Bureau of Investigation: The FBI has maintained files on numerous people, including celebrities such as Elvis Presley, Frank Sinatra, John Denver, John Lennon, Jane Fonda, Groucho Marx, Charlie Chaplin, the band MC5, Lou Costello, Sonny Bono, Bob Dylan, Michael Jackson, and Mickey Mantle. The files were collected for various reasons. Some of the subjects were investigated for alleged ties to the Communist party (Charlie Chaplin and Groucho Marx), or in connection with antiwar activities during the Vietnam War (John Denver, John Lennon, and Jane Fonda). Numerous celebrity files concern threats or extortion attempts against them (Sonny Bono, John Denver, John Lennon, Elvis Presley, Michael Jackson, Mickey Mantle, Groucho Marx, and Frank Sinatra).
Document 9: Federal Bureau of Investigation: During the September 11, 2001 attacks on the World Trade Center, FBI agent Leonard W. Hatton Jr. was killed during the rescue effort while helping the rescue personnel evacuate the occupants of the South Tower and stayed when it collapsed. Within months after the attacks, FBI Director Robert Mueller, who had been sworn in a week before the attacks, called for a re-engineering of FBI structure and operations. He made countering every federal crime a top priority, including the prevention of terrorism, countering foreign intelligence operations, addressing cyber security threats, other high-tech crimes, protecting civil rights, combating public corruption, organized crime, white-collar crime, and major acts of violent crime.
Document 10: Federal Bureau of Investigation: The USA PATRIOT Act increased the powers allotted to the FBI, especially in wiretapping and monitoring of Internet activity. One of the most controversial provisions of the act is the so-called sneak and peek provision, granting the FBI powers to search a house while the residents are away, and not requiring them to notify the residents for several weeks afterwards. Under the PATRIOT Act's provisions, the FBI also resumed inquiring into the library records of those who are suspected of terrorism (something it had supposedly not done since the 1970s).
Document 11: Federal Bureau of Investigation: During the 1950s and 1960s, FBI officials became increasingly concerned about the influence of civil rights leaders, whom they believed had communist ties or were unduly influenced by them. In 1956, for example, Hoover sent an open letter denouncing Dr. T.R.M. Howard, a civil rights leader, surgeon, and wealthy entrepreneur in Mississippi who had criticized FBI inaction in solving recent murders of George W. Lee, Emmett Till, and other blacks in the South. The FBI carried out controversial domestic surveillance in an operation it called the COINTELPRO, which was short for "COunter-INTELligence PROgram." It was to investigate and disrupt the activities of dissident political organizations within the United States, including both militant and non-violent organizations. Among its targets was the Southern Christian Leadership Conference, a leading civil rights organization with clergy leadership.
Document 12: Federal Bureau of Investigation: The Federal Bureau of Investigation (FBI) is the domestic intelligence and security service of the United States, which simultaneously serves as the nation's prime federal law enforcement organization. Operating under the jurisdiction of the U.S. Department of Justice, FBI is concurrently a member of the U.S. Intelligence Community and reports to both the Attorney General and the Director of National Intelligence. A leading U.S. counterterrorism, counterintelligence, and criminal investigative organization, FBI has jurisdiction over violations of more than 200 categories of federal crimes.
Document 13: Federal Bureau of Investigation: FBI Directors are appointed by the President of the United States. They must be confirmed by the United States Senate and serve a term of office of five years, with a maximum of ten years, if reappointed, unless they resign or are fired by the President before their term ends. J. Edgar Hoover, appointed by Calvin Coolidge in 1924, was by far the longest-serving director, serving until his death in 1972. In 1968, Congress passed legislation as part of the Omnibus Crime Control and Safe Streets Act Pub.L. 90–351, June 19, 1968, 82 Stat. 197 that specified a 10-year limit, a maximum of two 5-year terms, for future FBI Directors, as well as requiring Senate confirmation of appointees. As the incumbent, this legislation did not apply to Hoover, only to his successors. The current FBI Director is James B. Comey, who was appointed in 2013 by Barack Obama.
Document 14: Federal Bureau of Investigation: Beginning in the 1940s and continuing into the 1970s, the bureau investigated cases of espionage against the United States and its allies. Eight Nazi agents who had planned sabotage operations against American targets were arrested, and six were executed (Ex parte Quirin) under their sentences. Also during this time, a joint US/UK code-breaking effort (the Venona project)—with which the FBI was heavily involved—broke Soviet diplomatic and intelligence communications codes, allowing the US and British governments to read Soviet communications. This effort confirmed the existence of Americans working in the United States for Soviet intelligence. Hoover was administering this project but failed to notify the Central Intelligence Agency (CIA) until 1952. Another notable case is the arrest of Soviet spy Rudolf Abel in 1957. The discovery of Soviet spies operating in the US allowed Hoover to pursue his longstanding obsession with the threat he perceived from the American Left, ranging from Communist Party of the United States of America (CPUSA) union organizers to American liberals.
Document 15: Federal Bureau of Investigation: J. Edgar Hoover served as Director from 1924 to 1972, a combined 48 years with the BOI, DOI, and FBI. He was chiefly responsible for creating the Scientific Crime Detection Laboratory, or the FBI Laboratory, which officially opened in 1932, as part of his work to professionalize investigations by the government. Hoover was substantially involved in most major cases and projects that the FBI handled during his tenure. After Hoover's death, Congress passed legislation that limited the tenure of future FBI Directors to ten years.
