"they're gonna get guns anyway, let's not do anything" is a bad argument. if guns are not controlled, 100% of school shooters that want a gun will get a gun.
if guns are a huge pain in the ass to obtain, and if warning signs are identified that deny access to certain risky individuals, gun control is working. EVEN IF determined sick fucks still get guns, if you stopped SOME, you saved lives.
of course, the black market should also be targeted and shut down.
shooters strike unexpectedly and at vulnerable, unprepared people. do you expect to arm every grade schooler and their teachers?
i don't need to post statistics and shit. common sense is enough.
p.s. good people who want guns for self-defense would still be able to get them. if you can prove you're a loving father who just wants protect his daughter, you'd get a fucking gun!
just not freaks who go on Facebook rants about killing Christians or narcissists who post videos about killing girls that rejected him! in almost all shootings of the past decade, there were SIGNS that if the gun sellers had known about, would not have sold guns to them!
