>> He called the cops and since they didn’t respond immediately, as a citizen, he has the right to defend property and make citizens arrest.
It wasn’t his fault the criminals didn’t surrender and ran. Give the man a medal! <<
You’re asserting they ran? My understanding was no self-respecting Texan would ever shoot someone in the back. Maybe I’m just too old-fashioned, but his only defense would seem to be that they charged him in response.
That wouldn't be his only defense, not in Texas. But in the event, one was shot in the chest, so he wasn't running away, the other was shot in the side, so he probably wasn't running away either, but may have been turning to do so, or turning to flank the defender.
