For poll, assume you are not martial arts expert, but rather a 65 year old, overweight joe, and you have no less than lethal weapons on you (like pepper spray or stun gun, etc.). Also assume that if you are brandishing at any point, you are currently warning verbally as well. When it says no warning, it means no advanced warning before drawing (but was too long to include that description in the poll.) Assume the guy is too old to think of outrunning the attacker.
Criticism of the guy in the video was that he wasn't situationally aware, which is true, but having gone through a long thread the other day, it seems nearly everyone has no limit on how close you'll allow someone to get to you, at night, vs. a suspicious/hostile character (in hoody here). So really what difference would it have made had he seen the guy, except to be in the hand to knife fight slightly earlier. In the other one, we assumed an older victim vs a 23 yo attacker.
Assume for sake of argument, the victim saw him coming, was armed with IWB glock, was 65 years old, had no formal martial arts training, and the young guy coming at him says virtually nothing and transitions to stabbing the victim as soon as the victim is within stabbing distance, keeping the knife hidden until that point.
I got some "blah, blah, blah" response to the Tueller drill argument and disparity of force, saying it's difficult to establish, and you'd be locked up for murder, but here's the Tueller drill in action right before our eyes. How close are you going to let this hooded character approach you, at night, on the street, with no words spoken between you (not announcing a robbery or attack)?
I'm posting this to give a bit more reality to a similar scenario, and because Bad Bob says he prefers actual videos to analyze. I fully appreciate that as the victim, you not only want to survive, but stay out of jail and not go bankrupt with lawyer fees. It's no doubt a big concern. I'm also including a poll, so that the silent readers can chime in with their vote. Maybe others would intervene, but just didn't speak up. I also realize there's no specific legal limit to how close someone can get to you before you defend your personal space, your safety zone.
Side issue for the scenario might also be, if you plan on going to a pub, do you forsake your right to carry a lethal weapon, rendering you defenseless as you leave the pub (assuming you plan to be under the legal blood limit of .08 used for driving the whole night.)
Also, I realize people are going to say that their choice isn't included, but the poll is very limited in how much you can write, etc., so just bear with the choices, and pick the best one. The real question is how early can you move to deadly force by brandishing your gun and keeping someone at a safe distance from you, and/or is this simply not legally possible or morally justifiable in your mind until the attack is under way. Only weapon on you is a gun.
