As a matter of interest... I looked up how to get statistics, and found The Center for Disease Control, which allows you to select areas...

I asked for:

10 Leading Causes of Violence-Related Injury Deaths, United States
1999 - 2007, All Races, Both Sexes...ages from 18-85
The top two were:
1)Suicide
Firearm
148,193

2)Homicide
Firearm
97,768

That's for 8 years...and it is only DEATHS..not gunshot wounds which were not fatal.

Total, 245,971... divided by 8...30,745 per year...divided by 365 = about 84 per day, most of which are only 'local statistics'.

Leave out suicides..(though family & friends might wish that a gun had not been handy).. and it's 'only' about 1/3 the total..maybe 25-30 per day.

Mass homicides are only a temporary spike in daily statistics. I wonder what the NRA thinks of those figures?
