Nonsense.  Since 1993, the gun ownership has doubled, and the gun death rate has dropped by half.

About half of gun deaths in this country are suicides, and the largest segment of those are white males over 65.

Of the non-suicide gun deaths, approximately 55% are black on black and 17% Hispanic on Hispanic in the inner cites.  Only about 28% of the non-suicide gun-related deaths occur outside the inner cities controlled by Democrats that have the strictest gun control laws.  72% of the gun deaths are related to gangs and drugs.
