Or they'll assume correctly that the teachers know very little about how to properly use a firearm during an intense situation. There is a reason military and police train during intense situations and not just target shooting. The sign is a fucking joke made by a group that doesn't know shit about the real world outside their cult of gun ownership. The second sign is even less effective than the first.

I am a gun owner, I support proper regulations. The ownership cult is an issue. The cult thinks the second sign is great just because guns are involved.

Everyone already knows nearly all school campuses have been gun free zones since the days of Columbine. The media has had plenty of coverage proving even armed officers on campus have let shooters do what they want instead of intervening, because they were scared. People are also aware now that police are not required to actually "protect" and "serve" like their slogan, so the first sign does nothing. The second sign just looks like a shitty meme made by someone that thinks they are a "badass". It makes it look like a joke.

Weird how these teenage shooters are cold, mechanical, min-maxing, number-crunching killing machines... but they always pick their own school as the highest-ROI target.

It must be the tactical advantage of knowing the hallways.

Or... They're deep in a mental health crisis and actively want to die, and see the attack as a two-fer: kill the cause of my suffering, and then die to either myself or the police.

I'm sure a sign that serves as a daily reminder that "There's plenty of ammo here, your targets will stand their ground and not run, and you will definitely die instead of getting captured" will deter them at the earliest possible moment: Once they're already at the school, committed to dying, and packing heat.
