Just saw an unmarked black '12 Mustang police car in Chesapeake on Cedar. Factors to note:
1. ILLEGALLY dark tinted windows, sides and rear.
2. Chrome/black cylindrical antennae located center, forward on trunk lid.
3. Stock FM antennae still in place (or it looks like the stocker)
4. Uniformed officer driving
5. Tint too dark to see any strobe lights.
6. Regular VA plates
7. Very clean car for black paint
The thing that got my attention was the Red Bull can sized chrome/black antenna on the trunk and the way too dark windows. Not many around here have tint that dark unless they have out of state tags. The regular VA tag had me fooled for a minute until I pulled up next to him and with enough light coming through the his windshield saw the uniform.
Watch out, they are out there!
