yes it does, look at chicago they have the strictist gun laws in the country and they only have 500+ homicides a year, only. Besides the fact that they have 500 homicides a year, gun countrol is clearly working there.
Having good grip and pulling the trigger straight to the rear while lining up your front and rear sights, while shooting your criminal who has pulled a gun on you in a criminal fashion, equals good gun control that has thwarted gun violence! (inhale now)
