[Q]: Mariah Carey  undeterred by last yearâs performance  will take to the stage once again in Times Square to ring in the new year on live TV.
The star  along with Dick Clark Productions  issued a joint statement on Friday announcing  Carey  as the headliner for âDick Clarkâs New Yearâs Rockinâ Eve with Ryan Seacrestâ broadcast.
Careyâs manager blamed the production and technical difficulties that producers knowingly failed to fix. Dick Clark Productions called the accusations âoutrageous and frankly absurd.â  Carey  eventually broke her silence on the troubled performance  saying she was âmortifiedâ and that she intended to take a break from social media.
Now it seems as though everyone is ready to put the messy past behind them.  Carey  will join the likes of Britney Spears  Nick Jonas  Kelly Clarkson and Shawn Mendes as the world rings in 2018.
 Careyâs  forthcoming New Yearâs Eve performance will top an already merry holiday season for the star. In addition to performing her annual Christmas tour   Careyâs  famous single âAll I Want For Christmas Is Youâ has been played more than 100 million times this month alone  according to Forbes.

[Q]: EASTERN GHOUTA  Syria (Reuters) - His brow dripping with blood and his skin caked with brick dust   Abu Abdallah  was pulled out from under the rubble of  his  house near Damascus after  it  was blown up in an air raid.
 He  was lucky to survive the bomb that fell while  he  was having breakfast  dropped by one of the countless warplanes that emergency workers say have pounded the rebel-held Syrian enclave of Eastern Ghouta in recent days.
 His  three-year-old son was not so fortunate.
âWe were sitting around  eating â said Abu Abdallah - a sobriquet meaning â Abdallah âs fatherâ - as  he  recalled Tuesdayâs strike. âMy son wanted to use the toilet  so his mother took him. Then the missile came down.â
âI was under the rubble... and my head was bent down  I couldnât raise it â said  Abu Abdallah   who declined to give  his  full name. âI said thatâs it  this will be the end of  me .â

 Abu Abdallah  26   comes from the eastern Ghouta village of Marj al-Sultan  which the Syrian army recaptured from insurgents in late 2015.  He  had moved deeper into the enclave to the town of Saqba with  his  family to try to escape the bombing.
âNow itâs still not clear what we will do â  he  said.  His  family is staying with relatives while  he  recovers from a head injury and a back strain.
âThe (world) should have mercy on these children and women because they have nothing to do with the fighting â Abu Abdallah said. âIf they want to fight  let them go fight on the frontlines. But why are they bombing us?â

[Q]: Officer Tyler Beck shot and killed Scout Schultz  a computer engineering student  after police at the Atlanta school received a 911 call about a “suspicious person on campus.” The caller described the suspect as an intoxicated white male with long blonde hair and blue jeans who was wielding a knife — and possibly a gun.
In an interview  Stewart said  Beck  “had only been on the force a little over a year ” and had no law enforcement experience before that.  He  said  Beck  had not received well-regarded Crisis Intervention Team (CIT) training to deal with suicidal or mentally fragile suspects.
“It would seem that you would make sure at least campus police officers have all of the mental health training possible  (training) that’s easily available ”  he  said.
Actually  he said  one of  Beck ’s colleagues “did a good job of talking with Scout ” and the other cops were likely surprised that  Beck  discharged  his  weapon.
Georgia Tech has said  Beck  is on paid leave pending the outcome of an investigation into the shooting. In response to a query about  Beck 's training  the school referred USA TODAY to a series of statements on the shooting that did not specifically address training.
Ryan Powell  spokesman for the Georgia Peace Officer Standards and Training Council  which coordinates police training statewide  said  Beck  graduated last year from a basic law enforcement course mandated for all Georgia police officers.
But  Beck  didn’t take part in the more extensive  40-hour CIT course that since 2004 has trained nearly 11 000 law enforcement officers statewide. The course is recommended for 20% of all officers throughout Georgia.
He said video of the shooting suggested that the training benefited  Beck ’s colleagues  who calmed Schultz down during the confrontation and used the student’s first name. “Those officers were saying exactly what the CIT trainers are trained to say ” Powell said. “They were saying things like  ‘Hey  Scout  we aren’t here to hurt you — please put down the weapon.’”
He couldn’t be sure that  Beck ’s colleagues were trained in CIT  but said a CIT official who had seen video of the confrontation told him  “Those guys were saying exactly what we train them to say.”
Powell hesitated to second-guess  Beck ’s actions  noting that the standard for using deadly force amounts to this: If an officer is in fear of great bodily harm or death — to himself or others — he’s justified in shooting.
