One police sergeant, whose hair pretty much turned a dashing shade of grey during my rookie year, can’t stand it “when the idiot officer, empty-handed, approaches the suspect and talks him out of the gun he’s been pointing at the officer’s head.”
Whoa, big no no.
Rule number one, never go to a gunfight empty-handed.
Rule number two, bad guy points gun at cop, bad guy dies.
The moral of the story is if you want your protagonist to look brave by walking up empty-handed to a loaded gun pointing at his or her chest, realize that, in this case, brave equals stupid.
