So indict “John Doe” on the refusal to identify and trespassing or whatever they allegedly caught him doing, and make with a trial already. It’s up to the government to show evidence of being guilty of anything else. Not up to “John Doe” to prove innocence of anything else.

He was caught trespassing - as in 'caught in the act'. He has refused to identify himself - and until he does, he is in essence; holding himself hostage. As per Utah Code of Criminal Procedure Chapter 7

77-7-15. Authority of peace officer to stop and question suspect -- Grounds. A peace officer may stop any person in a public place when he has a reasonable suspicion to believe he has committed or is in the act of committing or is attempting to commit a public offense and may demand his name, address and an explanation of his actions.

There is no stipulation stating "unless the person just doesn't feel like it".
