In 2013 CDC say: https://en.wikipedia.org/wiki/Gun_violence_in_the_United_Sta...
> in 2013, firearms (excluding BB and pellet guns) were used in
> 84,258 nonfatal injuries (26.65 per 100,000 U.S. citizens) [2] and
> 11,208 deaths by homicide (3.5 per 100,000),[3]
> 21,175 by suicide with a firearm,[4]
> 505 deaths due to accidental discharge of a firearm,[4] and
> 281 deaths due to firearms-use with "undetermined intent"[5] for a total of 33,169 deaths related to firearms (excluding firearm deaths due to legal intervention).
That would be about 90 per day. US police shoot and kill about 1,000 people per year, but weirdly they don't count so we don't have robust numbers.
With all honesty that figure should've made any sensible person give it the sniff test even if it was released by the NRA yet alone by the Brady Campaign. So either the total report is BS, the figures weren't for fatalities but for all casualties or your memory isn't as good as you think it is or any combination of all of the above.
Edit: I was referring to a report by the Brady Campaign that in 2012 there were over 90K gun deaths in that particular year. I saw this recently on the news, and the stats stuck in my head for obvious reasons.
