We have the internet now. No way they could pull off another Dallas type assassination. Probably even another 9/11 would not be accepted.
I don’t think the internet is enough to stop them. I think the only thing that will stop these people is locking them up. That’s why it is critical to lock up anyone, no matter how “elite”, who is guilty of these crimes.
What allows them to get away with it is not the lack of the internet, or the lack of evidence. It’s the lack of will to prosecute.
