The one that bugs me the most is when a cop/detective/agent needs to talk to/arrest a guy, and they call out his name before they are close enough to physically grab him. What happens? Dude runs, and then there's a chase. Like, seriously, the guy's not expecting you. Sometimes there are TWO of you. Get close enough to grab him.

The worst are where they see the guy and approach closer but still don't wait until there's enough room to avoid a chase. So annoying.
