Why anyone would intentionally make their car look like a police car is beyond me. I understand those who buy retired police cars on the cheap, but I'm talking about the ones who add stuff to further the trickery. Driving a marked car is a pain in the butt when you're just trying to get from A to B. Brake tapping and 5-10mph under the speed limit sure is fun when you just want to get home.
So I got pulled over several years ago by a fake police officer. I figured something was up when I saw his "uniform" but his car looked authentic enough, plus, there are several wanna be officers who put a spotlight on their car but most wouldn't be that bold. Once I got a closer look though I was VERY nervous and it was before I made the transition to armed citizen so i was basically at his mercy. He very quickly warned me about my speed and told me to get on my way. Never asked for ID or anything. I called 911 and they nailed him in a couple of minutes. Anyone crazy enough to impersonate an officer AND pull people over on the side of the interstate isn't someone who should be mixing with the general public.
