FWIW the view from a maturing martial artist.
15ft is a push off the rear leg and a cross step...2 seconds, tops. If your only defensive preparation is a gun, and a person with training can touch your torso or your arm between the elbow and shoulder before you are on target and squeezing the trigger, it’s over.
A punk who needs to “show his nuts”, is unlikely to have any kind of training, other than knockout club. He put on a show and ended up getting shown, happy ending.
If he had actually been a dangerous person, he would have said nothing, pretended to need to walk past them to get somewhere, and he’s right there, he’s already taken someone out, and he’s controlling the other adult.
Whatever your firearm expertise, basic training can help you have proper focus, keep you acting after being hit, and give you the ability to gain enough space to turn a gun on someone who is at zero distance. It might actually be helpful, to practice falling to the ground on purpose with your feet towards your target... it makes you a smaller target and more difficult to reach and control by a closer, gives you more seconds to clear your weapon and line it up...you can even fend off a man with your feet who’s on top of you, while shooting upward.
The most useful self defense tool requires no physical training at all. Go for a daily walk were you practice 360 degree awareness while looking straight ahead. Do not turn your head, focus your eyes on nothing, but be aware of everything. If someone is suddenly focusing undue attention to you, or alters their course to intercept your path, sometimes you’re feeling it in your stomach before you ever actually see it with your eyes. You’ll know you’re on track when someone who’s eyeballing you produces almost a physical sense like being touched. Once you get the focus, do your best to do this 24-7 when you’re out in the world... it isn’t learning this that’s hard, it’s maintaining it. When you start getting tired, you will start missing things.
After you get in the habit, if you’re walking through a crowd your heightened attention and the general population’s lower attention span may make you feel like you’re walking in a world of sleepwalkers, and if there is another person in that crowd with heightened attention, like someone who’s hunting for something or someone, they stand out.
Bruce Lee quote: “Attention is the highest form of martial art.”
Last piece of advice: If you’ve learned to trust your instincts when to warn you, then trust your instincts when to act. Initiative is everything, it’s better to act too soon than too late, it’s better to be judged as presumptious and being a hot head then to be dead. When to make your move is a judgement call that every individual has to make for themselves. One of my early teachers told me, that if someone’s coming up to you saying “I’m going to kill you” the only sound that should ever come out of his mouth, is “I”. An attentive man would already know where the situation was leading, and be prepared to bear the responsibility for the consequences of acting to cut it off before it ever began.
Take what helps, flush the rest...T.
The large men are repossessing a car...the small girl with the black belt is the owner of the car who is delinquent on her payments...but still it illustrates a point awful well.
I choose to call it Mountain Sized Man With Mega Mouth Confronted by Korean Kitten with Confidence and Skill...and Look Who's Crying
I grant you, the girl is in the wrong because she defaulted on her car payment. But its case in point of the wide gulf between looking powerful and being powerful.
Women in particular will love this...LOL
