Gun Control & RKBA

mass shooting tracker is an admitted propagandist pushing an ideology.

History and the plurality of criminologists say banning guns will do absolutely nothing. Like I said before, if banning handguns in places like Mexico, Brazil, Venezuela, Australia didn't work, what makes you think it will work here? Gangs in Australia have no problem getting handguns, and it is even easier for them to get basement made machine guns. Heroin has been banned for over a century. You also ignore another issue. Handguns are used to defend innocents than they are used in criminal use. The actual number varies, but most criminologists put it in the neighborhood of 500K per year. True, a few thousand of them require the trigger being pulled and even fewer result in the death of the bad guy, but you get the point. There is more evidence that removing lead from gasoline decreased crime than banning guns.

China's mass murder problem has more to do with their very shitty mental health system. Since they tend to attack elementary schools and preschools, so the death toll is pretty high.
Banning handguns, or any other infringement on the vast majority of law-abiding citizens, will do nothing but piss people off. Even the residents of places South Chicago that live under the gangs' thumbs are seeing it for what it is, political theater by corrupt and apathetic politicians who are in mutually beneficial relationships with these gangs.
Banning something from law abiding target shooters, collectors, or whomever, for the slim chance it might get stolen and used by some far away gang, will get you the literal and electoral middle finger.

"there are probably some economic steps....but they are not gun related" That sounds like you are more about banning guns than actually caring about fixing the problem. Since the "war on..." phrase is used, let's go with war on drug gangs. That requires a strategic war plan that takes on the triad of any military enemy. Chicago took down the management of the large gangs, leaving soldiers to kill for promotion and start their own little gangs. We saw how that went.
The triad is: finance, recruitment, communications.
End the drug war. Treat addiction as a health issue, not a criminal issue. Repeal the federal ban on things like pot. I personally don't like pot, but I'm not a moral busybody either. That takes away much of the money.
massive infrastructure projects. We have to get lead out of the water just like we did the air. Schools that are falling apart and graduates functional illiterates can't be tolerated in any society. Also, more skilled trades training along with humanities and university STEM. This will increase employment Walkable mixed residential and business neighborhoods that will even allow urban agriculture, especially greenhouses that can grow fresh vegies year around. That would push the prices down and improve nutrition. Giving better alternatives, and positive role models other than the few that make obscene amounts of money playing children's games while trashing their health. That denies the gangs new recruits.

Of course, before we can do this we have to take on the hardest problem of all. Political corruption from the Detroit school board that squaders money on bullshit to Chicago city council that protects the gangs who keep them in office. They all have to go.
