Bikers do live in AZ
Evidently, they are now considered a "street gang" (as opposed to a social club). This designation allows the incompetent county attorney to add charges to ordinary crimes because of who is a friend of whom. I have no problem with prosecuting crime. I do have a problem with guilt by association-type crimes, like those now on the table. Your membership is not a crime; your conspiracy (regardless of membership) is a different matter. But, bikers are bad, and "criminal street gang" makes for a splashy headline. Welcome to Arizona.
[Ed. note: I saw one of our AZ club members outside my office yesterday morning - commuting, not stalking. Naturally, the one time I do not have my camera on me...]
