They took that off the books a little bit ago.
http://publicsafety.utah.gov/bci/FAQ.html#2If I get stopped by a police officer, do I, as a permit holder, have to tell the officer that I have a gun in my possession? Although there is no legal requirement to identify yourself to a law enforcement officer, it is recommended to do so.
This kinda pisses me off though:
..so when does "innocent until proven guilt" come into play?If an officer finds or sees a gun on your person during their contact with you, and you have not identified yourself as a permit holder in legal possession of a firearm, the officer must assume you are carrying the gun illegally and will take defensive action.
