If you’re implying that the grand jury was racist… no this wasn’t racist Texans letting a white guy off, that’s a fact.
I don’t know the details of this case but I’m as outraged as everyone else that it was charged with manslaughter.
The key factors in thinking about use of force to respond to a threat are immediacy, blamelessness, and proportionality. Is the threat immediate? Is the defender a prudent person who didn’t do anything to cause or escalate the situation? Is the force proportionate? From my read of the news article, it sounds like there wasn’t immediacy. The threat was over, he was firing at unidentified targets, and it made no sense.
I think Texas does allow defense of property. Most states don’t, and even in states that do, it’s going to be a very thin legal defense.
