Florida shooting

Teachers and staff at Marjory Stoneman Douglas High School go back to the school today, more than a week after the massacre there killed 17 people and reignited the national debate on guns. And everyone's reeling over the news that the armed deputy stationed on the Parkland, Florida, campus didn't immediately go in the building while a gunman killed students and staff inside. School resource officer Scot Peterson stayed outside for four minutes during the six-minute shooting spree, authorities said. Broward County Sheriff Scott Israel said the revelation makes him "sick to my stomach" because Peterson could have stopped the shooter. Peterson resigned.

Trump talk President Donald Trump speaks at the Conservative Political Action Committee, better known as CPAC. The ongoing gun debate is expected to be front and center in his remarks after Trump suggested arming teachers to help end the violence. Teachers have taken to social media pushing back on that idea with the hashtag #ArmMeWith, asking for an increase in classroom resources, not the ability to carry guns in school.
