Oklahoma educators react to Connecticut massacre

“I don't think there's a perfect way to be prepared for it,” Norman Superintendent Joe Siano said. “Any time there's an incident like that, it gives you pause and reason to reflect.”

Evaluating procedures and training staff members must be a continuous process, Siano said.

“It's one of those situations where you never can do enough,” he said.

Police officers train every summer in one of the Norman schools, practicing what it would be like to track down a shooter, Siano said. Every principal has been through specialized training about how to react to a shooting.

“Do all those things prepare you for every event? No,” he said. “But I think they give you a sense of how to react.”

Midwest City-Del City Schools has a number of safety measures in place, school district spokeswoman Stacey Boyer said. The district employs off-duty police officers as security staff. All schools have visitor-management systems and secured doors. Staff and students go through lockdown and evacuation drills, and employees train for school shooter scenarios. A crisis-management team is ready at any time, and district officials are also looking into using security card access at schools, Boyer said.
