I think that everyone on here has made good points. What I see in this video is something that could happen very easily with my friends and I. We all being together feeling maybe stronger than we are and instead of just giving up our wallets loosing maybe a 100 bucks, we think we can over power the person and gain the upper hand. Now we would all probably be carrying, but if we werent I am sure our false security would still get in our way.
Adrenaline is a very powerful thing, witnessing it first hand a mans strength, just like the perps in this video, can triple and him releasing that weapon is like trying to break it free of steel vise grips. When I was about 9 years old I had a big travel trailer tongue slip of its jack and land on my foot. My Father in the midst of an adrenaline filled flury, picked up what would be equal to lifting a small cars back end off the ground, lifted this trailor's tongue weight off my foot by himself.
In this situation I almost feel that four men on one guy is too much. All jockeying for postion is leaving some men in the open just like what happened. Two men on that one perp the out come could have been vastly different and you see after the fight becomes two on one the victims gain control of the weapon.
I feel that in this situation if you are with out your own firearm and you cant get a shot off without endangering your mates, I think the best is to give up the wallets look for an opening upon the perps move to retrieve the thrown money or wallets, and wait to call for a police assistance. Or maybe get a shot off when the assailent is turning to leave.
There will be an opening. But like I stated before it is hard to go in with four guys at once. Someone will be left open so in the safety of your buddies,time is the perps enemy. Wait for your chance. I believe with my friends that have been trained, we could do something and all think on the same lines of what the others are all thinking. But if I was in the situation with 4 friends I havent spent years training with and know how they will react or what their abilities are, I would try to take control by speaking to everyone to calm down give him what he wants and if the opening comes take it, but wait. Sit on the situation. All alot harder said than done.
