I'll be quick on that point. If you get Supreme Court decisions that document that certain groups are organized crime groups, that may settle the matter. On the other hand, as you know, you can get into a situation where groups change over time and what was once an organized crime group may not be an organized crime group at a future date. So it's tricky.
There are many who are highly critical of the Hells Angels, who suggest that the best way to approach them is individually and not as an organized crime group. But that's a long debate for another day.
