What magical powers do you think a police officer has to tell "us" from "them" before he asks for ID? All I'm saying is that a police officer needs to assume that every stranger is a potential danger until he DOES know who it is.
I live in the US not a POS place like Canada.
I am not required in any way to give an ID or tell a policeman who I am. If you are it's because you live in a POS place. (probably why you have a higher homicide rate than Wyoming even though 59.7% of the people here have guns)
