Some pro-gun facts you can use:

…guns accidentally killed just 606 people in the U.S. in the most recent reporting year. That’s about 1/55th the number of people killed in traffic accidents.

 

“Guns now kill about 30,000 Americans annually.” Though that many people do die annually from gunshots, over 19,000 of them were suicides. When more than 60% of deaths are mental health related, the suicide tool of choice becomes irrelevant. Canada shares many cultural elements with the United States, has a nearly identical suicide rate, but a lower gun ownership rate. The World Health Organization notes that severely depressed Canadians opt to use poison to kill themselves.

Proposing solutions requires understanding the problem. From health and criminological statistics we know that of all gun deaths about 61% are suicides, 2% are accidents, another 1% are legal interventions, and the other 36% are criminal actions – intentional homicides. The overwhelming majority of homicides are gangland slayings, as Pittsburgh’s own East Hills Bloods and Fulton Block Boyz will attest. Ponder this for a minute. If gangs and people of mental fragility were dealt with, 97% of all gun deaths would disappear. Obviously this isn’t a gun control problem. Drugs and gangs aren’t an NRA problem. Mental instability isn’t a consumer protection, reckless gun owner, or even a child-proofing problem (only 62 children were accidentally killed with guns in 2010, and some of those deaths are of a suspicious nature).
