If you truly understand the law and how things work, you will know we can't really say much about that. Can you prove that he "witnessed," a murder? Can you prove, or do we know that he was aware someone died? You do know murder is a very specific term, yes? Is this particular case a "Murder," according to Texas law?
DETAILS matter, and we don't know details, and we don't know what his defense to any charges might be. So telling me that my "Argument," is outdated is incorrect.
I know my specificity to the details will get passed some people in here, but I went to lawschool, and there is a lot about this case we don't know. That Texas law you point to is not a slam dunk......it might be, but not off of the little bit of info released at this point.
You say he didn't talk until he was a person of interest. And your point? Maybe up till police contacted him there was nothing to talk about? Yea.....I could go that route as his attorney, and it would be up to prosecutor s to prove otherwise.
