I'm adding to that the bad gun use cliche of person having the gun kicked out of their hands before they ever get to fire, particularly if the person is a police officer or FBI agent (thinking here of x-files, where I swear they never pulled a gun but they lost it. I watched that show for four seasons and I don't think I ever saw an agent successfully fire a firearm).

Can we please assume that people who have guns might actually know how to fire them?
