Example Input: We know that  Nikolas Cruz  wasn't hiding a thing about  his  killing rage in the months and even years before the Florida school massacre.
According to the best British newspaper in America  the Daily Mail   Nikolas Cruz  abused his ex and sold knives out of a lunchbox.  He  was disciplined by the school 25 times and finally expelled.
Good Morning America could not pass up an interview with survivor Ariana Lopez. In her circle  everybody knew that  Cruz  was dangerous.  He  didn't bother to hide it. According to  Ms. Lopez  Cruz  was signaling  his  rage and murderous feelings like mad.
Lopez made it clear during her interview that  Cruz 's problematic behavior and mental health issues were on clear display at school. 'He used to sell knives out of his lunch box  which I thought was insane. You can't have knives  this is a school'  said Lopez of  Cruz . 'He would be like  "hey guys  want some knives?"' One of the incidents that led to his being disciplined was a fight in September 2016. Footage of the brawl emerged over the weekend.  Cruz  was suspended for two days as a result of the fight  which was over a former girlfriend.
This changes the picture completely: what the hell were the school counselors and police authorities doing while  Cruz  was signaling murderous intentions? There is an air of looming tragedy over the Florida school killings  and secretly  many people knew or suspected what was to come.
Any competent teacher  administrator  school cop  or counselor should have seen the signs and should have diverted  Cruz  into a protected environment where  he  could be educated and monitored. If  his  friend Ariana knew he was selling knives  so did dozens of other kids  teachers  administrators  and all the rest. No person in authority acted responsibly. They just kicked the can down the road.
There is no mystery about the Nikolas Cruzes of the world. They have been around forever. It's just that they were spotted and taken care of with discipline and  yes  with love and acceptance  whether they deserved it or not. If they acted out  they were punished appropriately  and if they looked dangerous  they were diverted to activities where they could do no harm.
That's what fathering is all about  and that is what the ancient phrase "in loco parentis" means.  Cruz  should have been effectively disciplined from childhood onward  but  he  was allowed to grow into a raging menace  recognized by other students and by numerous adults.
Example Output: Cruz told everybody: 'I'm a killer!'

Example Input: The trend to this point gives a distinct edge to the Democrats. While roughly the same number of lawmakers in both parties are leaving their seats to run for higher office  just nine House Democrats are retiring outright or have already resigned  compared with 24 Republicans. (House members running for other offices often count as retirements  because itâs usually impractical or illegal to run for multiple positions at the same time.) Including those members who are leaving to run for another office  there will be 17 open House seats vacated by Democrats and 35 for Republicans. Democratic victories last November in gubernatorial and state legislative races in Virginia and New Jersey could spur more retirements among Republicans worried about the national political environment under Trump. And although Democrats must defend far more Senate seats than Republicans in 2018âincluding several in states that Donald Trump wonâall of the partyâs incumbents are currently running for reelection. The retirements of Corker and Flake  along with a Democratic victory in Decemberâs special election in Alabama  give Democrats an outside chance at retaking the Senate majority. In the House  theyâll need to pick up 24 seats  and the more Republicans retire in districts that  Hillary Clinton  carried last year  the more the GOP majority is at risk. Data sources: Each districtâs presidential-election results are from the Daily Kos. House and Senate election results are from the Associated Press.
2012 Senate election: +3.9 Flake He decided to leave after a single term rather than wage what would have been a brutal fight for reelection  first in a primary against a hard-right Trump backer  Kelli Ward  and then  if he won  against a centrist Democrat  Representative Kyrsten Sinema  in the general election. Flake had lost his base in Arizona: His criticism of Trump in his recent book  Conscience of a Conservative  alienated the presidentâs GOP backers  while his conservative voting record put off Democrats. Orrin Hatch  Utah 2016 presidential election: +17.9 Trump over Hillary Clinton; +23.8 Trump over Evan McMullin
2014 Senate election: +10.24 Franken Under pressure from fellow Democrats  Franken announced in December he would resign âin the coming weeksâ after multiple women came forward to accuse him of inappropriate sexual behavior. Most of the allegations involved Franken groping women while taking a photo. His resignation means there will be a special Senate election in 2018 in a state that Hillary Clinton barely carried in 2016. House Republicans Retiring Outright Steve Helber / AP Bob Goodlatte  Virginia 6th district 2016 presidential election: +24.8 Trump
2016 House election: +0.52 Issa Issa in January became one of the most recognizable House Republicans to announce his retirement. A former chairman of the Oversight and Government Reform Committee  he served as the chief congressional inquisitor of the Obama administration for several years. Issa is annually ranked as one of the wealthiest members of Congress  having co-founded the company behind the Viper car alarm (for which he famously provided the voice). But he was in for the fight of his life to win reelection after nearly losing in 2016 in a district that  Hillary Clinton  carried over Donald Trump.
