Police Cars Rammed in Dangerous Series of Crimes!

Six ramming incidents in recent weeks have targeted unoccupied police vehicles; with stolen cars rigged to slam into the target vehicles. This is far more than a crazy prank — it could easily get someone killed. Please analyze these surveillance images, showing one of the suspects on foot, as well as two suspect vehicles (a pickup truck and a light colored sedan). There is a reward for information leading to an arrest.
