Ramsey Dewey (and friends) can be quite funny when they put their mind to it. This video compares and tries to replicate two self defense videos which teach one how to defend against multiple opponents with guns:
I will say, though, that while the humor is entirely correct, and moreover that fighting multiple opponents with guns is probably not going to end well, there was an interesting point that wasn’t highlighted here. In Ramsey’s reproduction, the gunmen kept a safe distance from Ramsey. There was a curious self-defense video I saw which made the interesting point that while trained people will indeed keep a safe distance when they have guns, trained people rarely rob people with guns. They can make money honestly.
The sort of people who rob others on the street with guns don’t have training, and moreover use the gun primarily to assert their dominance and only secondarily as a weapon. And indeed, security footage does show that criminals often do wave guns right in people’s faces rather than keeping a safe distance. This doesn’t change the right thing to do when threatened with a gun (since the smallest mistake can result in being killed) but it is an interesting point of human psychology.
