I've got to chime in here and I know you guy's are going to think I'm crazy and maybe I am but here goes. Along with the school resource officer, their were 3 more deputies that responded while the shooter was still active. Now the way I see it, they are trained to use "tactics" to access the school or they should have been familiar with this particular school, but nobody went in, until two or three city police officers arrived and they went in and the shooting had stopped. Now I worked for a Podunk department here in Wisc. and our deputies go thru "Active Shooter" training at the local high school twice a year along with the city police, EMS, and fire departments. I would hope all sheriffs departments and city police throughout this nation would have gone thru some sort of similar training with all the school shootings we have had in this country, and when you are paid to do a job, do it!
