Input: Consider 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.

Input: Consider Input: It has been a long time since two teams induced as many sofa spasms as the New England Patriots and Pittsburgh Steelers did  with those three false endings in the last two minutes. You thought  finally  the NFL is all about the game again. But just then  the skin-crawly headline came across the bottom of the screen  turning attention away from Tom Brady and Ben Roethlisberger to an old pot-belly named Jerry Richardson.
[Panthers owner Jerry Richardson announces plan to sell team amid NFL investigation]
Yet the viewer’s head swiveled back and forth between the Patriots-Steelers epic in the icing rain  and the alleged fetishes and racial attitudes of Carolina Panthers owner  Richardson  in  his  owner suite. On Friday  the Panthers announced that Richardson was being investigated for workplace abuses  and by Sunday morning  the story had exploded when Sports Illustrated published a host of sordid specific accusations ranging from sexual harassment to using a racial slur against an employee. These included Richardson supposedly asking to shave the legs of female employees and demanding to examine their backsides in their jeans.
But that wasn’t the end of the NFL day. Not thirty minutes after the final play in Pittsburgh  with fans still filing out of the stadium  came the seismic announcement that  Richardson  will be selling the Panthers  the franchise  he  has owned since it was founded in 1993. No explanation was offered  or needed. You have to assume that the disclosures were going to get uglier.
[Analysis: Forget the catch rule. The league has a replay problem] 
Richardson  is a perfect example of the extent to which the sheer girths of owners’ egos are eclipsing what should be the NFL’s true narrative: the game. Their incessant internecine rivalries and power struggles have become a chronic story line. It was  Richardson  who set the poisonous current tone of management-player relations  when  he  declared during the 2011 collective bargaining that the owners had “a [expletive] deal and we’re going to take back our league and [expletive] do something about it.” It was  Richardson  who  inexplicably grown arrogant on  his  Hardees franchise money  sat across a table and barked at Peyton Manning: “Do I need to help you read a revenue chart  son? Because I don’t know if you know how to read that.”
Richardson  no doubt  is also capable of individual kindness  and other owners will profess sorrow over his decision to sell  and wax nostalgic over the fact that he once caught passes from Johnny Unitas with the 1959-60 Baltimore Colts.  Richardson  is a self-made man  the first player since George Halas to acquire an ownership stake. But  Richardson   sadly  has acted as a toxic hardliner devoted to ensuring that no other player would ever be treated like a partner or equal.

Input: Consider Input: In Narino  fighters from the ELN attacked members of the Rural Resistance  ombudsmen  Carlos Alfonso Negret  said in a report. The Rural Resistance are FARC dissidents who refused to demobilize following the peace deal.
“The ombudsman’s office visited the area and was able to determine that there was an exchange of fire between the group that calls itself Rural Resistance and the ELN  ” Negret  told journalists. “There was crossfire that killed 13 people.”
Neither the report nor  Negret  specified how many of the dead were civilians.
But  Negret  says some 800 former guerrillas did not demobilize  while other security sources and thinktanks put the number of dissident ex-FARC at between 700 and 1 300.
