Down in south Texas I get a lot of poser cop cars running around. Civillians that dress out a crown vic or impala to look like an unmarked cop car. Usually if it's a late model and too suspicious looking I can slow up and check for a tax exempt plate and continue on.
But the other day I saw two HPD cars and a very convincing white unmarked unit with a regular Texas plate in a restaraunt parking lot. It was a white crown vic with very dark windows. 3 solid radio antennaes on the rear deck. Couldn't tell if it had lights on the rear dash.
I know HPD and HCS have white unmarked units very similar to this one but they always have tax exempt plates.
Does anyone know how this unmarked police car registration policy works. A buddy at work believes that any LEO can purchase a police package cruiser on his own and install all the goodies on it he wants with private registration. I'm sure there must be somebody out there who knows more about this stuff than my friend at work. Any ideas?
