Hes in complete denial.
1) Washington DC, hand gun ban 1976
2) Chicago Illinois, hand gun ban 1982, how did that work out? All mayors since 1931 have been democrats.

In fact, the number of killings rose by 156 percent — at a time when murders nationally increased by just 32 percent. For a while, the city vied regularly for the title of murder capital of America.
Chicago followed a similar course. In the decade after it outlawed handguns, murders jumped by 41 percent, compared with an 18 percent rise in the entire United States.
One problem is that the bans didn't actually have any discernible effect on the availability of guns to people with felonious intent. As with drugs and hookers, when there is a demand for guns, there will always be a supply."
