It's not, but pointing to DC as an example that gun laws don't work ignores a number of significant factors; specifically, the fact that guns are easily purchased just outside of the District's small expanse.
NYC's another interesting data point (but merely that) -- violent crime rate is roughly the same as Phoenix's... one city with a heavily armed citizenry and one virtually defenseless, same results. Obviously, other factors matter more.
If you go down the list of US cities with violent crime problems in order, the unmistakable trend is they're all at the bottom end of the economic spectrum. Safe bet that the local unemployment rate has a lot more to do with crime than gun laws.
