Broward County sheriff's deputies will now carry AR-15 rifles while on school campuses following the shooting at Marjory Stoneman Douglas High School in Parkland, Florida, last week, Sheriff Scott Israel announced today. The new policy was implemented Wednesday morning. In lieu of gun lockers, the only time deputies will not be "slinging a rifle" is when the firearm is locked in police vehicles, Israel said. The rifles will not be fully automatic and will only be handled by deputies who are "trained and qualified" to operate them, Israel said.
