I think some arm of the federal government could sweep Chicago and the other cities and legitimately confiscate the weapons from gang members who are felons, and aren't most of them?
So, take the gangs guns away, jail the perps and save many lives. Why don't they do it?
One reason they don't, in Chicago at least, is that the gangs wield enormous political power. Bonus question: Guess which party they support?
Democrats pay women to breed thugs and vote Democrat.
