Careful about your language and running your mouth
On 20/20 or some such show there was a guy who, after calling the police to no avail, decided to confront neighbors when their karaoke/birthday party went too late. He regularly carried a gun and spare mag and did so when he walked down the street. When he got there he had the police on the line and video rolling, and confronted the neighbors as planned. It was a party so there were a quite a few adults there. As he confronted the homeowner, other adults came forward as well (but were spread out) - at one point there were about 15 adult partiers in the vid. The complainant repeatedly stated "Get back, I am in fear for my life. I can stand my ground". One idiot actually started towards him and was shot. Two more tried to subdue the shooter and were also shot. The shooter claimed that he mistook a flashlight in the homeowner's belt for a weapon.
I think the guy that initially was shot was an idiot for going toward the shooter. I think the shooter was mistakenly thinking that the mere presence of other people amounted to disparity of force.
The prosecutors jumped all over the specific verbiage he used "I'm in fear for my life" and "I can stand my ground" - saying it was contrived to exactly fit with TX law. They brought in witnesses that testified about him giving advice to others about claiming such giving a person justification for lethal force and also shooting a neighborhood dog that got into his yard - apparently the neighbors didn't think he was right in the head.
He's now serving 40 yrs. I agree with the verdict, from what was presented.
Be careful of advice you give and the steps you take/when you take them if you ever find yourself in a defensive encounter.
