If you want to live in the past, that's up to you. But in the modern day, shooters are targeting gun free zones because they know they are gun free.
Ass-suming causations not in evidence. I uh, don't think anybody looks at a "gun free zone" sign and thinks, "Hey, that's my cue to shoot guns". Such signs were put up *AFTER* rampant shootings made them necessary, not before.
So you're cherrypicking your own causation and running with it as if it were established causation. Case in point, 'splain this --- school shooters are always alienated males. If a "gun free zone" sign is what, no pun intended, triggers shootings, which still doesn't explain the shootings before they got put there, why don't we have an equal number of female shooters? Do not the signs read the same way to males and females?
And an administrator or educator who has a CC is already trained in gun safety. It's about living in the real world, not the fantasy in your head where a gun free zone sign will make shooters stay away. Actually, it draws them here.
Same specious ass-sumption. See above.
It's funny how leftists like to mock conservatives for not following science. Then you turn around and think signs and laws will stop shooters from killing people. Here's a ball, look, it's bouncy ...
STILL same specious ass-sumption. And an ironic twist since science (data) actually disproves the sign mythology anyway.
