exactly. he lied after the fact, he didn't call for a while, he didn't get a lawyer right away. He did lots and lots of things wrong that looked suspicious and still got off.
If you walked outside to go get something out of your vehicle that you left in it, and you saw these guys trying to jack your car and confronted them, then they didn't run and tried to escalate it and make you think you are in imminent fear for your life, I don't see how that wouldn't be justified.
For some people a car is all they have, maybe their way of life and it deserves to be protected. Insurance is nice to have but some people can't afford full coverage insurance. And like the people trying to steal a car, who may be down on their luck, the guy whose care they are trying to steal may be on the verge of losing everything but is trying to scrape by doing things the right way. In the end it is a personal decision to decide whether or not it is worth it. That is what life is made of.
