Well we shall soon find out won't we?
Personally, I find your response to this a little bit frightening. This certainly should NOT be a 'slam dunk' and less than two decades ago, the answer was clearly and legally "No, you do NOT have to identify yourself".
These days, I'm not so sure. What does scare me is that there are a large number of people who believe you ARE required to identify yourself and that believe this is acceptable.
"Your papers please!"
I believe the disposition will be that you have to identify yourself to the police and the police must have probable cause that you are involved in a crime. If you are asked to identify yourself and it is subsequently shown that the police did it just to hastle you, then they will be repremanded.
Some time ago a car with plainclothes police stopped me walking along the highway. I showed identification and they gave me a ride home to confirm my address. I was told I fit the description of a man they were looking for seen in the area where I was walking. (I was in the wrong place at the wrong time.) Since my story checked out, I ended up with a free ride home. If I decided I had no identification, I am certain these officers would have taken me in. Were my rights violated? I did not think so. Would I have helped the police if I could? Yes. Have I ever been falsely accused by the police? No, Does it happen? Of course. So get those cops off the street.
