This is why. Davey Jones released their street addresses, make and models of their cars and tag #'s in an attempt to invoke retaliation against them.
The Jersey Guys are generally supportive of the NJSP, but they are critical when it's warranted. This was especially the case when Trooper Higbey ran a stop sign in SJ at high speed with no lights or sirens, and killed 2 teenage girls when he hit the van they were driving. The Trooper in question was initially only issued a careless driving ticket after an "internal investigation". After much pressure by the media, and especially the JG's, the investigation was broadened and he has since been indicted on other charges. If it was you or I that hit them, we would've been locked up on the spot.
On the other hand, they have been supportive of the Trooper driving Corzio during the crash.
