I wonder why? :banghead:
Aside from the fact that it's a commercial?
Here's how it would actually go down:
Victim: "Honey, call 911. Tell them I am armed and am detaining the suspect of an attempted knife attack. Describe what I look like."
LEO to Victim: "Put your weapon down and step back towards my voice." (Victin complies)
LEO's partner to knife attacker: "Lay down on the ground, hands on top of your head."
After both are cuffed, they'll sort things out then. Whatever you do, never take your firearm off the perp except to lay it on the ground under the direction of the law enforcement officer. If he's super cool, he may tell you to holster it, but don't count on it - even if you're his next-door neighbor.
