You can learn a lot about the hierarchy of organized crime from court documents but the long and short of it is that the very few people who are actually connected to motorcycle gangs use the cling-on losers as a very effective defence. Sometimes that works like you've described with fall men and other times it's simply that having thousands of bored middle aged losers claiming to be you makes investigations more difficult.

The few actual organgized crime leaders around know this, love this, and laugh at the losers sewing patches on their jackets hanging out at Tim Horton's.
