Not LEO, wasn't going to post, but, on the subject of impersonators, I know a lady here in WA who (used to?) own a range in Spokane, who had a story about how her son was smarter than she thought, because he declined the invitation to go out joy riding with his buddies who were using a couple of the new LED flashlight, one red and one blue, to trick motorists into pulling over. Evidently ( as in, "from the evidence"), one in right hand, the other in the left, flash them alternately, and people will pull over. So far as I know, the boys just laughed their heads off as they drove by, but as a real-life illustration in an NRA Refuse To Be A Victim class about "feel free to drive to a well-lit area before pulling over", it's hard to beat.
