How old are you? You are not aware of the crime bill from 1994 to 2004. You will need to cite the DV state with firearms and violence. Here is a stat and cite for you.

 In the most recent 2010 edition of Lott’s book, “More Guns Less Crime,” Lott concludes that “[a]llowing citizens to carry concealed handguns reduces violent crimes, and the reductions coincide very closely with the number of concealed-handgun permits issued.”

I am not saying I am not for any regulations but the catch phrase "common sense gun laws" Often are not common sense. Felons owning guns no I don't agree with that. Domestic violence offenders owning guns no I don't agree with that either. That is not gun control but rather people control which is where the problem lies. But saying a law abiding citizen can't own a semi auto rifle because it looks scary I will never agree with that. I use AR15's for work and for play. I shoot a lot of different shooting sports such a 3 gun, USPSA, Steel Challenge etc.
