which makes one wonder; if the police ask you for your identification, and you’ve done nothing wrong, do you have to give them your id?[/quote]

Depends on whether you want to escalate or mitigate the situation. You will most likely be on the shorter end of the stick if the situation become confrontational and physical. Getting your teeth knocked in or your face rearranged or even getting yourself killed is not worth it – even if the punks get prosecuted for their crimes (and that’s a big if).
