[Q]: 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.

[Q]: Prince Harry  refused to take part in the Royal Familyâs traditional Boxing Day shoot on Tuesday so as not to upset  his  âpart-veganâ activist fiancÃ©e  according to reports.
Gamekeepers at the Sandringham estate  where  Harry  first joined  his  family at the annual shoot more than 20 years ago  were âstunnedâ by the princeâs decision  according to The Sun.
â Harry  loves it and has always been out there on  Boxing Day . But if it means breaking with long-standing royal traditions to avoid upsetting her  so be it. Itâs fair to say that there are some pretty stunned faces around here.â
A friend of  Harryâs  said: âIf Meghanâs not comfortable with  him  doing the shoot   he  wouldnât want to upset her.â
On Wednesday  Prince Harry and the BBC were criticised for producing a politicised âinterviewâ with Barack Obama in which the former president launched a thinly-veiled attack on his successor Donald J. Trump.

[Q]: Smoke rises after an air strike during fighting between members of the Syrian Democratic Forces and Islamic State militants in Raqqa  Syria  August 15  2017. REUTERS/Zohra Bensemra/File Photo
In the end  IS suffered its most decisive defeat and watched their self-proclaimed caliphate evaporate in Iraq  then in Syria as Kurdish-led forces retook Raqqa  ISâs urban stronghold there.
The battle for  Raqqa  which became  ISâs operational base in Syria  had a different feel to it as U.S.-backed Kurds and Arabs in the Syrian Democratic Forces (SDF) tightened their siege.
In the weeks before  Raqqaâs  fall in October  young female SDF fighters faced off against hardened militants and suffered losses. But that did not curb their enthusiasm and some said they would eventually like to join Kurdish PKK militants in Turkey and help advance their 33-year-old insurgency there.
After ISâs defeat in Raqqa   Raqqa residents  formed a council to run the city but  they  had no budget when it was first set up  just residents streaming into  their  tin  run-down headquarters demanding everything from instant jobs to getting  their  damaged farmland back.
The Kurdish groups who led the fight against Islamic State in its former capital  Raqqa  must now navigate a complex peace to avoid ethnic tension with the cityâs Arab majority and to secure critical U.S. aid.
So  life for  Raqqa âs victors will remain fraught with risk.
