If you've been pulled for FOR speeding, then the cop can simply say so, because he has probable cause that you committed a crime: your radar gun reading. THAT is the probable cause. What they can't do is look at you and decide they simply want to know who you are, pull you over, and just like the Gestapo, demand your papers. They must have a reason for stopping you, and without it, they do not have legal standing to force you to identify yourself. Yes, you can make everything easier by complying with their unlawful demand.
They must have probable cause, but there is currently no requirement to disclose it to the person being stopped as far as I know. If you have an actual legal source, like a relevant law or court case, then post it.
