Good question. I'm not a police officer. But I've seen that TV show Cops. When a cop escorts a suspect, it's often with the cop's holstered gun between him and the bad guy. Why do they do that? Shouldn't it be standard procedure for the cop to stand so his gun is not next to the suspect? Perhaps some LEO Freeper can address this.
Here's what I mean. Take a look at the cop on the right. His gun is just inches away from the suspect's hands. If that suspect can wiggle out of his cuffs, he can get that gun in a second.
