CIA ops
Do you remember Unabomber and OKC Bomber? They were caught.
They were CIA.
I think CIA set them up and then outed them.
They didn't need them anymore.
They were a liability.
At some point the CIA operative will start to talk.
CIA tries to stop them before they do either by Suiciding them or "catching" them after an op.
thanks
Also for the innocent people these desperate people are hurting/killing to make a statement.
