I am very confused? Like, we have legal "gangs", they are called Clubs, Non-Profits and Political Orgs. By definition a true gang ->(define:gang = "an organised group of criminals") When a group of people commits crime and the intent of their group is to commit crime- how do you 'legalize' that- I see lots of flowery language with very little concrete information as to -how-. Like you issue a permit to the crips and bloods and say "Hey guys you're all legal now, just dont kill each other okay"? I really don't follow the logic on this.
