There is no penalty not to sign in the state of Utah. The officer has the discretion to put “refused to sign” and send him on his way, OR arrest him if he sees fit. The officer did neither. He is in trouble, rightfully so.
“OR arrest him if he sees fit. The officer did neither.”
So, what you do think the “turn around, put your hands behind your back” meant?
That the officer wanted to play pattycake?
