In Texas, there would be no case.
And, if you screw up and kill somebody just because he made a mistake and came in your front door rather than his own, you could very well find you'd messed with the wrong family.
Always, always find out their surname first!
At the moment this guy probably doesn't have a big problem but it'll cost him something to answer the suit, but he's lucky. In New Jersey he'd be meeting the Profacci family, or maybe the successors to the Gambinos (as a couple of Vietnamese thugs are discovering locked up for trying to rob a local mobster's wife at a hair salon).
What you want to do after one of these killings is NOT SWAGGER but avoid becoming a target.
And honor killings? Those Arabs don't reserve them just for their sl__+_ daughters.
There won't be any case in any other state of the USA, either. This reeking bullshit of a case will be tossed out sooner or later, or the jury will award 1 penny as a judgment against the defendant, just to illustrate the absurdity of the complaint...
This is a civil suit, not criminal. Don't they have dumb ass civil suit lawyers in Texas too?
