The constitution calls for well-regulated militias. I'm all for well-regulated militias, I was a member of one for years. Chicago should be able to "well-regulated" it's guns if it wants to.
What I'd like and what I am willing to live with are two different things.
If Joe were dictator, the ATF would be going door to door confiscating every last gun. But sensibly, I know that's not practical. We need to phase guns out slowly. Make it harder to get new ones out there, hold the gun makers responsible for their irresponsible marketing, making having a gun such a pain that people eventually give them up.
