I was riding with 3 friends on Route 1 going to MotoGP last summer. When the four of us were told to pull over for speeding, one of us (the smart one) bolted. The CHP officer repeatedly asked the remaining three "who is your friend" and "where does he live". Um, officer, never seen that guy before in my life. Point is, there was nothing he could do for "withholding information about another person". They cannot coerce you into snitching. I'd just say that several people have access to the bike and it could have been anyone of them. Hard to say, really?!
ps. the reason "they" go after "us" is because they know we will pay
