That case was big news around here when the acquittal came down. It is a pretty appalling case.
When I was a kid a neighbor spotted some miscreant vandalizing his car at night. Neighbor shot and killed the miscreant. The miscreant was, IIRC, just up to some dingus teenage hijinks. This was in what was at the time a very safe, upper middle class suburb, and by that I mean the entire development of 40,000 people were pretty uniformly white and upper middle class, with few or no surrounding areas with higher crime rates. Violent crime was nil, most other crimes were nil as well. Unfortunately for the miscreant, vandalizing a car is considered "criminal mischief", he was doing it at night, and therefore the neighbor's actions possibly fell under that statute. I don't believe the neighbor was ever even charged with a crime. Maybe he should have been.
I'm not sure how I would rewrite this statute, but I'm not a fan of it as written. Like Tam alluded earlier, there is a widespread belief in Texas that you can up and shoot someone for messing with your car. That's not the case, but people don't bother to read and understand the statute.
