A caller had mentioned on a local morning radio talk show what I think is a pretty good idea.
Hire retired police. They are in a lot of cases still in their 40’s. Not to mention trained and have experience. And may be looking for such a position. They can be in plain clothes and armed. The locality can make it well known that the schools are protected.
Great idea - they can also be the guidance counselors. Who else (aside from cops and soldiers) know first-hand, and have the experience and the guts to tell the little darlings what the right track is and what happens when they stray?
