None of what you said is persuasive towards not having a gun - it is mostly reciting google.
The Tueller drill models ranged tactics. It compares how long it takes to draw a sidearm vs how quickly a knife fighter can close the range between them. If someone attempts to pull a gun on you at short range (a few meters, precisely how far depends on speed), there are techniques you can use to disarm them. However, they require repetitive practice under a skilled instructor to be used effectively. Their odds of success go down against an opponent trained to counter them. The best defense against a gun attack for someone without proper self-defense training is to run like hell. Distance and motion decrease accuracy. Even if you are armed with a gun, run like hell to cover before returning fire and, if you are not a trained soldier or a law enforcement professional, and if you have any opportunity to escape, do not waste it returning fire. If someone already has a gun trained on you at short range, do what they say until you have an opportunity to escape, at which point run like hell. Originally Posted by Centaur
