I was in maine last week, and spotted two state troopers with Radar Antena's mounted forward/backwards side by side between the drivers and back doors on the outside of the cruiser.
I believe the cruiser was using stalker dual radar or something similar.
If I find a picture I will post it.
Does this allow them to have more range to detect speeds? I've never seen this before and I've probably seen over two hundred different police cruisers.
