Seriously, John Kerry’s group was infiltrated by the FBI, and yet he still got away with treason and came close to being POTUS. Certainly, we can be as successful doing the lawful thing as he was committing treason.
These organizations would most certainly be infiltrated by these organizations. And what they would find is people legally preparing in a very militant fashion - while hearing messages of solidarity with all our rank-and-file military and law enforcement.
However, they would also find an organization that could be activated at a moment's notice.
Recall the German "hunting clubs" that formed immediately prior to WWII.
