Unfortunately, the US is more gun happy than most countries. There is a statistically irrational fear of getting shot and most people who are killed are killed by someone they know, not a random stranger.
That means cops have to be more vigilant about guns.
They also leave out the number of incidents and the breakdown of those. I am sure there are 10s of thousands of times the police do not overreact compared to times they do.
I wish I could take credit for this, but as Chris Rock said....
I know it's hard being a cop … But some jobs can't have bad apples. Some jobs, everybody gotta be good. Like, pilots. American Airlines can't be like, 'You know, most of our pilots like to land, we just got a few bad apples that like to crash into mountains.'
That means cops have to be more vigilant about guns.
