>>13669577I had witnessed someone trying to kill two people with a weapon. Similar but not exact situation, but the principle of action or inaction applies. The perpetrator wasn't aware of me, but the two other people looked right at me. I was relatively sure I wasn't on any meaningful recording device at that point in my walk, but the circumstances were extreme enough that I could have potentially been linked with the perp if they had failed in their attempt, or so I thought at the time. That is why I was not sure if Bystander Laws / Good Samaritan Laws would defend me because politics of law is more important than law a lot of the time. You do not have to be guilty, you just have to be found guilty.
I'm hard-hearted and don't panic, I calmly walked up behind them, locked their left leg, right wrist and neck with my arms to disarm them. I wrenched them until they dropped their weapon, and then Judo threw them onto the hard ground. They were temporary paralyzed by the immaculate throw because they landed directly on their spine. I know nothing about martial arts aside from practical application of theory. That is to say, be practical and better than the other guy.
TL:DR; I didn't get in trouble because I acted. I can not say the same if I hadn't acted. Read the book Republic.
