California has some of the strictest gun laws in the nation. The type of weapons used are banned specifically in that state. What good did it do? Chicago is a war zone, and they probably DO have the strictest gun laws. I still believe we should blame the individual and not the method, but there is such outcry when events like this occur that I'm aware the opinion isn't popular. directly after the aftermath.
And...good guys with guns did stop the rampage. The "militarized" police force had just enough force to end it.
Near where I live, a man disarmed and detained an armed robber a few days back in a busy restaurant I'm not saying the idiot was going to start shooting patrons, but he also never had the chance to do so. You didn't hear about that on the national media.
Plain and simple, making something illegal will not stop a person from using that something if they want to use it badly enough.
Mass shootings aside, more people are killed yearly in plain old "I got pissed at somebody and decided to shoot them after they walked out of the club" incidents. Mass shootings are only popular news because of the fact that national media and politicians can use them for their own benefit. Othrwise, you'd hear as much about them as any shooting in Chicago or Detroit or Miami or wherever. They're brought up and argued over because of their magnitude.
As far as making something illegal "cutting a supply line," ask me how many times we gave Narcan for heroin overdoses the other day at work. If the police can bust a smuggling ring at a moment's notice, why is there any crime? The police don't have a chance against the drug trade, and would have just as much chance against a gun ring. And I'm not downing the police! I love the police, my brother-in-law is a US Marshal. Often, their hands are tied.
