Cops in every school???? How did that work just last week?
NO, NO, NO!
The answer to armed guards in schools is armed TEACHERS!
Vetted, trained, volunteers with stipends, insurance, legal representation.
A concealed weapon RIGHT THERE in the CLASSROOM! Hallway, Gym.
No uniforms to give the identity of the guards away.
Not ONE guard for an entire school, but multiple undercover guards (teachers) all over the school.
Who wants to protect the kids more than teachers?
The concealed, subdued strategy could work well especially creating a psychological impact only if strict OPSEC is observed - do not want it leaking out as to who is armed, how and where. Would go far towards making anyone contemplating doing something stupid think more than twice. Since libs love signs so much, I got one for them -
ARMED STAFF
ON PREMISES
That would add to the psyops on would-be attackers. A sign with better wording could probably be devised, but that's what I came up with off the top of my head.
