I would also like to see less violence in the US, but I don't think gun control, sensible or otherwise, will do anything about it mostly because it affects the people who are not the problem.
It is like the mental health red herring. It started off with Wayne La Pierre scapegoating, with his resgistry, the least violent, least political powerful (along with ill defined) group of our country, now the antis jumped on his bandwagon.
Sensible is a meaningless term. Tasmania's licensing and registration (Australia has a federal system similar to ours) system did nothing to prevent Port Author. The killer did not have a license and one of the rifles was stolen from a police evidence locker. There have been mass murders since then. New Zealand also had mass shooting during that same ten year period, did nothing, and had the same result as Australia.
More effective would be:
end zoning ordnances that prevent walkable communities including to well paying jobs and stores that sell real food. After living in Japan and Korea, I noticed that their cities don't have the same flight to the suburbs.
End drug prohibition, addiction is a public health issue, and should not be a criminal issue. Best way to take guns away from the gangs is to take away their money. They didn't have guns before GCA and the WoD even though all they needed was a Sears catalog and a money order. There wasn't that much profit in hot hub caps after school.
raise the min wage and have it adjust for inflation. Add that to pulling out of NAFTA, GATT, and shit can TPP. and put our tariffs back up.
Removing lead from gasoline seems to be the most effective, certainly more effective than any gun law. And social conservatives clutch their pearls when I say, ending corporal punishment. Yes, I am anti spanking.
That isn't to say that I think we should go back to Vermont pre NFA. I do think NFA and other current laws need to be made sensible before we create new ones.
