Eye was just questioning, not speculating, so you agree within your statement (as you've stated it) that if there is organization they should be fully persecuted under the law? If so, Eye agree with you. Then again, you're probably right. Nobody funds them or stands by while they do as they wish. Good thing the FBI and other international intel organizations would never be able to figure it out huh?
Not organization. Criminal organization. That is the only way they would be prosecuted by the RICO act.
Also, questioning and speculating are the same thing, at least in the context in your post. You were speculating.
If there is anything they can prosecute BLM or Antifa for under the law, they are welcome to try. Any legal ramifications will be tough to come by for both movements. They can prosecute individuals for individual acts, sure, but to take any prosecutorial actions against either would more than likely be unsuccessful. Even labeling Antifa a terrorist organization is a major stretch at the very least as Trump has tried to do.
Good thing money in this day and age is so hard to trace.
