Google “police weapon retention.”

I once had a really interesting conversation with the gun dealer who armed John Allen Mohammed and Lee Boyd Malvo. He had been a CHL for many years and was used to carrying his gun when he was out in public. Then one night he experienced a road rage incident in a parking lot where another driver became incensed at him and got out of his car to confront him. The man was not armed. During the melee, the gun dealer told me he spent 90% of his energy just trying to secure his firearm, so scared was he that this man would gain access to it. Eventually, he was able to break away and, both men exhausted, the fight ended.

After that night, he told me, he never carried a gun again.
