Certainly true. And when you CAN bugout, by all means do so. I'm certainly glad this guy was neither effective nor armed, and that you left before something worse happened.
oh yeah, I've gotten more use from ny Nike-Jitsu than anything else, it's gotten my out of a couple of potentially bad situations.
One was when I was walking home from work, and was passing by some housing projects, not terrible places, but not the best. I had three young guys, one actually quite young, the other two old enough to be genuinely dangerous, especially working as a team. They confronted me and I took off, showed them that I could outrun them and they gave chase for a block or two. What struck me about that situation was how incompetent they actually were. Maybe it was their youth and inexperience, I dunno. But they confronted me without first surrounding me, without first trying to hit me or something. If they had done that, things might have ended differently. But they didn't and I escaped rather easily, all things considered. But I believe they were quite incompetent, as far as being street thugs.
I've had a handful of other, similar incidents, where people tried to confront me. One or two I ran, one time a guy tried to grab at me and I brushed him off and turned to confront him and he backed down while kinda laughing, one guy threatened me with a "gun" in his sweatshirt pocket. I told him I didn't have anything for him, he shrugged, and just turned and walked away. Weird. I don't know if he actually had a gun, I doubt it but I could be wrong.
There are some genuinely dangerous, scary folks out there and they cause trouble for people. Some of them are career criminals, and prey on people as a way of life. That is true. But there are a lot of wannabes who could be dangerous, but just aren't that good at it. So yeah, be careful, and be wary and aware and recognize that the scary dudes exist. But keep it in perspective and don't get excessively paranoid about it.
I sometimes think that the practice of training in the martial arts, and contemplating and thinking about self-defense and the dangers in the world, can magnify the dangers in our minds into something greater than it really is. Take it seriously, but don't let it make you paranoid.
