No. If he knew how to respond to the situation then he wouldn’t have started wrestling a guy with a gun in his hand.
I just want to make it as clear as possible that wrestling a guy with a gun in his hand is always a bad idea. I mean, if it’s just you and the gunman then fine – you’re taking your own life in your hands, and I think that’s your right. But there were like half a dozen other people in there whose lives mustache risked by laying hands on the gunman.
If you think that there’s situations like this where wrestling a guy with a gun in his hand is a good idea, then I’d request that you cite some sources on that. I double checked my assertions against police recommendations and security expert recommendations, which I think is a pretty good source. If you find better then I’ll happily concede the argument. Otherwise, I think your perspective is wrong, bad, dangerous, and puts people at risk.
My assumption that he placed peoples lives in danger is a sound one based on both reason and the experience of experts in the fields of security and law enforcement. This assumption is consistent with the fact that in this instance no one got hurt, because while the man’s actions vastly increased the risk of something bad happening, they did not ensure that something bad would happen. He rolled the dice and won. But he staked the lives of other innocent people on that die roll, and I think that is egregiously uncool.
It’s possible, but very unlikely. This is about risk again. There is some risk in letting the gunman go through the robbery. The risk that an armed robber will randomly commit homicide if unprovoked and allowed to proceed with the robbery is lower than the risk that an armed robber will commit homicide if attacked by one of his victims.
This is a completely rational and sensible approach to deciding what to do during an armed robbery and accords well with the recommendations of experts in the field.
All that set, you are exactly correct when you said that fight or flight instinct is in play when a robber starts waving a gun around, and yes no doubt mustache was inspired to stupidity by some very strong emotions.
Nonetheless, I’d like to strongly recommend against anyone imitating mustache because I honestly and sincerely think that he increased the risk of someone dying, and I would prefer people not die because of stupid decisions like that.
