I thought I had previously seen a thread on this topic on GPDO, but I can't find it. The short version is, can an LEO demand the ID of a passenger at a traffic stop? I have a work associate who was a passenger in such a situation. Nothing happened in the stop except a verbal warning, but she felt unsure about the situation. When I asked the acting chief of police about it, he responded that an officer may ask for ID from anyone at anytime, but a person can refuse if not under investigation, and even then the officer must be able to articulate probable cause. He also referred me to the State v. Allen decision. After reading through the decision I have determined two things. One, I admire you lawyers who have the patience, knowledge, and time to do that on a daily basis; its not something I would want to do. Two, apparently the US Supreme Court and Georgia Supreme Court have ruled that running background checks on passengers is OK since it falls under the umbrella of necessary for officer safety. What is not clear is what happens when a passenger refuses to present ID, or if they don't have one at all. I see the words, "request" and "ask" in the decision, but I did not see "demand." So, if I were driving with my wife as a passenger, and I was stopped for something like speeding, should I advise my wife to not present an ID if asked by a LEO? I know this is not concrete legal advice, but I would like to know the opinions (or experiences) of others before I am presented with such a situation. I also have concerns for my mother-in-law who does not have a driver's license, but is a very frequent passenger in various people's cars. She does have a photo ID, but as a passenger, she could very legitimately not have it with her one day (although that might be a slim chance, since she is one of those women with a purse full of everything everywhere she goes).
