[PAR35]

Is there some law in Texas that makes it illegal for one to possess a gun while under the influence?

Unlicensed carry in a bar is illegal in Texas, but that would suggest that he 1) didn't have a CCP, and 2) there was one on him rather than in his room. Neither of which is mentioned.

Unlicensed carry in a bar is illegal in Texas

Licensed carry in a bar is illegal in Texas.

Called the "51% rule" - If the establishment makes more 51% of their income from alcohol consumed on the premises (as opposed to a liqueur store where the rule does not apply), then carrying is now allowed.

and 2) there was one on him rather than in his room.
Neither of which is mentioned.

Good question and it isn’t clear. Somewhere I read he was
there for a 3-gun shoot. Thus the reason he had those guns
with him. There was one schedule for early Dec. but was
cancelled. You think he’d let the hotel know that he had
guns in his room.

Has to be something like that. Or the cops decided they weren’t taking any chances, locked him up on some BS knowing it’d get tossed and would worry about him getting a lawyer, down the road.

Which, under the circumstances, probably wouldn’t go too far anyway, in Texas.

Also, it sounds like he was at the hotel bar, not an actual bar. So even if there was a 51% sign posted, it's an incorrect posting and has no force of law. The only way a business can make a small part of it a 51% zone is by making it completely separate from the main, non-alcohol business.
Otherwise, the blue alcohol sign does prohibit any weapons in any establishment that serves alcohol.
