Two thirds of schools perform 'active shooter' drills

More than two thirds of school districts in the United States conduct “active shooter” exercises, but some are having difficulty threading the needle between scaring kids and informing them about how to react, according to the Associated Press.

Some schools make their drills very realistic, simulating the sounds of gunshots and using smoke and fake blood,” the AP reported. “In one case, armed police officers with weapons drawn burst into a Florida middle school, terrifying staff and students alike.”
