Consider the probability of bad things happening to elderly white guys who roam low-income minority neighborhoods. Consider the possibility that the cop thought she was dealing with a demented old guy who she didn't want ending up in a body bag on her shift.
Please. Are you trying to justify an unlawful search and seizure on the basis of police concern for the violated person's safety? Is the state here to make us all safe now? And if they choose to seize Americans off the street "for our own good" will you meekly climb into the SWAT van and hold hands and sing patriotic songs with your fellow formerly free but currently "unsafe" citizens?
You have surely drank the kool-aid, friend. You are exactly the kind of person I was referencing in my first post.
