No. No CHL no duty to notify.
I think the lesson here is not to trust the police to do what is right, but rather do what they are told. Just following orders.
Remember a policeman who has detained you for any reason is not your friend.
That begs the question. In TX, when can a police officer legally disarm you? I'm thinking mostly about traffic stops, but I'm also curious about other situations.
I thought that they needed to be informed prior to them just coming across it during a "search"?
You seem to know the whole story. Did the officer give the guy his gun back and the end of the stop? Does the state law there allow officers to temporarily disarm people during contacts? Is that state a must inform state?
