The feds would have no choice but to protect the schools as 300 million guns would be impossible to be gathered in even 1 generation. So, a school fortress with TSA type screening access and armed security in every access and hallway. Distinctive student garb/uniform that would making ID of an outsider immediate. No grouping of students allowed and hallway access strictly controlled.
Essentially think penitentiary, prison garb, full access screening ie: xray, strip search. Walk to class on allotted hallway lines. I think the snowflakes would melt, but this is essentially what full time protection would call for.
Probably not what the activists have in mind.
I like it,time to get strict with the “children”.
