Okay, let’s do it!
I think I’m in favor of making membership in a criminal organization . . . itself to be a criminal offense.
For example, if someone joins a motorcycle gang with a long record of criminal behavior, give them 9 months at home with an ankle bracelet. And absolutely, boredom is a big part of the punishment.
I mean, use RICO, and use it somewhat aggressively.
And yes, I’m aware this is unfair as some motorcycle gangs transition to more of a social club. However, I’m willing to tolerate a degree of unfairness.
But it has to be better evidence than a vague tattoo such as a clock.
