The U.S. homicide rate in 2010 (mostly but not exclusively with guns) was roughly 4.8 per 100,000 population, or roughly 50 in every million. So your chance of being killed by an American with a gun is about 1 in 20,000 each year. (It's considerably less if you stay away from drug gangs and especially if you don't infuriate a volatile relative or acquaintance who has gun handy.)

Too many shootings, but not quite like the TV shows. And remember how many guns are around.

By the way, the chance of being killed in an auto accident, also per person per annum, is about 1 in 90.
