Pointing at lack of firearms regulations in the US correlating to higher firearm violence does not imply causation. We had an assault weapons ban for 10 years that did nothing, and given that 98% of murders are from handguns (in 2011) and DC banned handguns for 30 years, you would expect DC to have low handgun violence, but it does not.

Pointing out places within the US where (some) guns are banned is a bad choice of example, unless you can't get in without being searched.
