so what legislation would you suggest? redundant laws that state that the air force should follow its own rules? banning assault rifles, which would've prevented civilian intervention? there is no way at all that this could have been prevented with more legislation, considering that the whole reason that this happened was a guy with some gears to grind against a church was able to get a gun because of a logistical error
the most that can and should happen is that some air force officials get tried for negligence, much less sacked immediately
Here's the loving deal because you can't seem to understand the point here. Obviously something went wrong with the legal process of barring him from firearm purchasing that directly resulted in him purchasing a firearm that he shot and killed 26 innocent people with. When people are calling for "Gun control", they mean an ambiguous fix to whatever the problem or error resulted in him being allowed to purchase a firearm. That's it. There's nothing beyond calling for an explanation of what necessarily went wrong so this doesn't happen again in this way.
"there is no way at all that this could have been prevented with more legislation" Is a lie, you have just about as much knowledge on saying this as the people you're attacking here. It's just that while you're preferring to entrench in your belief that literally nothing could have prevented this, everyone else is thinking on how exactly it could have been prevented.
