How Arizona schools deal with active shooter situations

As authorities in California continue to investigate a shooting rampage that left six dead and involved a school, there are concerns over how schools deal with similar situations.

December will mark five years since the mass shooting at Connecticut's Sandy Hook Elementary School. From that incident, schools we have learned many lessons, and locking down a school quickly is just one of them. Arizona schools all have a plan.

"One of the first thing I try to teach our administrators is believe it can happen," said James Dorer, who is the Chief Security Officer of Scottsdale Unified School District's 29 schools. Dorer has heard news accounts that the California school went into lockdown as soon as gunshots were heard, and that saved lives

"The benefit of a school administrator making that proactive decision, I think, is marvelous," said Dorer, who told schools that if they ever have a question put the school into lockdown, it can be sorted out later.

"I say I'd rather be wrong a hundred times than the one time we really should have gone into a lockdown and we didn't, 'cause were hesitating," said Dorer. "If nothing else, we go into lockdown and you realize it wasn't what we thought it could be, great. You just did your drill."

Laura Rennie, a mother, said she has great faith in Scottsdale Unifed School District's security.

"I know even for drop off or pickup, they're very particular about how that happens to make sure the children are safe, and you have to check in with front office to even be let into the building. I know my kids are safe during the day," said Rennie.
