It's very hard or impossible to police the internet. That's like sticking your head out a window in a blizzard and identifying a particular snowflake as it blows past. It seems no one from the public noticed or reported it to authorities. Police need tips from the public. Your point is made tho
You could make Faceache, Tiktok, etc, responsible for what they put out. It would be their legal responsibility to find this stuff and report it.
I bet you there are ways there are ways to find these people, but we have inept inexperienced idiots in the FBI and the DOJ
Likely, something is being done, but I was never a cyber expert. I know the FBI has notified Canadian police about certain occurrences. I've worked with some FBI agents who were top notch, but sadly, their command staff have been compromised.
Our federal & local LEOs have remained silent re domestic terrorism for ever … WHYte is that? Historians have documented the presence & rise of white separatists in all their forms It’s only when we have a McVeigh, it seems, that we have any expose’.
Excellent question. For which I do not have an excellent answer. I will note that a large group of U.S. law enforcement is actively involved in the enforcement of unpopular politicized policies and programs, as is some of the national guard. Marines? Military? We'll see. Waiting for a coup.
