Lessons learned from Columbine?

More on the Binghamton Massacre from NRO

Maybe or maybe not. I'm not going to Monday morning quarterback the response but I would like to know if the dept trains for the Active Shooter.

I would like to know if there is a Gun Free Zone sign on the front door of the place. Just another reason why citizens need to conceal carry. By the time the police get there it will likely be too late.

I'm glad the officer in the nursing home shooting didn't wait for backup because those patients were sitting ducks.
