The truly naïve notion is that the perfectly defenseless elementary school situation of a Sandy Hook, with its scary locked door and lines of beautiful floor-ceiling windows, can’t coexist in a country with completely porous borders, sleeper AQ cells, Gulan-style training camps in NY and PA, IRGC troops, Iraqi/Iranian/Palestinian/Egyptian ‘refugees, CAIR fanatics, and drug trunk lines from Central America through to Canada. Even someplace like Dayton, Ohio, apparently has over 200 gangs. Villainy lives within driving distance of most places now, unfortunately.
I think can’t should be can in the referenced thought.
You cannot have the perfect innocence of an elementary school left undefended ad infinitum and expect no consequences.
I don’t know why parents are comfortable with their children being undefended while the parents need keycard/CAC access.
