Lol agreed, I would now do things differently. But if I were in this guys shoes? I'm not sure. I may have called the police as soon as this guy got irate and was apparently drunk. I may not have directly intervened but I very well could have decided to get his LP# being that he was irate, intoxicated, and getting into a vehicle.
After this incident, if placed in a similar situation, I will try to be more "sneaky" and less obvious if I were to take down a plate number from someone who has already proven himself to be combative. Also, just like after the Zimmerman incident (not at all comparing the two in the least) I learned that if you are going to carry, perhaps toting some pepper spray as well would create some options if **** goes down.
