school safety

[Danzig]

we all know that schools and shootings are becoming a bigger problem. just had a shooting in ga yesterday. thankfully no one was injured.

in a previous job, i had to visit many places such as defense contractors, paper mills and the like. they all have a turnstile gate with badges for people who are to be admitted, and an intercom for everyone else. could also install a gate for the buses to go thru, and only the buses, much like a cable company had (copper a high priced commodity).
why don't we install those at schools? seems a simple fix to me. and relatively inexpensive compared to armed guards, etc, etc.
