I think it is a miracle that a Beslan-type elementary school/middle school/high school event perpetrated by Jihadists hasn’t happened yet. Most government schools have a “security” policy that begins and ends with a sign that says “all visitors are required to check in with the main office”. Sure, the statistics today say it’s pretty rare, I’m just surprised this doesn’t happen more often. These schools are wide open targets.
When I hear about schools going into “lock down” I always wonder what that means. If three guys showed up with shotguns, could they keep them out? Or would students and teachers just be trapped inside with the shooters?
