"This is my catchy quote." -Me

Literally all gun control accomplishes is giving police more reasons to send people to prison and strip their rights. That's the origins of gun control in the US. It was a method to strip free black people of their voting rights. It was introduced on a federal level to criminalize weapons associated with organized crime. It was used in the 60s and 70s to justify raids on dissidents; the assassination of Fred Hampton was executed under the pretense of a raid for illegal weapons, as one glaring example.

You're a fucking moron if you think that's why cops execute civilians in droves. It has nothing to do with the number of guns in America. America has always had tons of guns. This is a nation whose culture is significantly defined by the presence of firearms, yet hypermilitarized police executing noncompliant civilians with impunity is a relatively recent phenomenon. The incredible rise in police violence is almost entirely the fault of one man; Dave Grossman. He made millions off nationally touring and giving seminars to cops telling them to think like an occupying soldier. How death awaits around every corner. To kill them before they can kill you. And, because of that, police officers in America now have looser rules of engagement than American soldiers who occupied one of the most heavily-armed countries in the world. The actual threat probability has nothing to do with it. Police live and operate in a separate, self-defined reality.

And, further on how this country has always had guns. There was a time where even machine guns were incredibly easy to get. Mass shootings have not always happened. In fact, mass shootings as a phenomenon only really morphed into some kind of trend pretty much precisely when news media began turning into what it is today, focusing on sensationalism to scare audiences into viewership. And the more promotion that's been given to shooters, the more attention they get, the more airtime their crimes get, the more frequently they've happened. They happen in states with very strict gun control. They happened under the Clinton assault weapon ban. They happen within the conditions that are supposed to stop them because it is a cultural sickness. It's something happening not because these people have access to guns, but because murdering a whole bunch of people, inflicting the worst cultural nightmare of America, seems gratifying to them.
