My old LL Bean copy of a WWII bomber jacket would probably make these "educators" faint dead away.
No. It would give them a glorious opportunity to be Heroic and Save the Children and further instill in the children fear of guns and the military. The teachers feel elated and their lives justified.
I was recruited into the Navy by a first class petty officer who came to the high school in uniform, the old uniform, thirteen button Navy blue bell bottoms, white “Dixie cup” hat etc. He was a well built fellow and his blue jumper with the white stripe collar stretched skin tight over his muscles, kind of a beefy version of the Cracker Jack icon. I reckon the sight of such a creature on a school ground now would bring out a whole army of police.
