Problem is what would they say?
One thing that was pointed out in the thread is 613 Trucks is something like 11000 members. If even one percent are assholes that is 110 people. That is a lot of douchebaggery.
Regarding MNR, I doubt they would say anything anyways. Odds are they will keep an eye out but unless they catch them doing anything its a free country. Now I could see someone joining the group to observe.
Oh and two assholes on the road today. Guess what they had in their rear window...
