They don't even care if they get caught red-handed anymore.
They realize that every time they get busted and nothing happens it only encourages their followers and intimidates their opponents. And they get bolder.
I predict that soon we are going to be seeing rapidly escalating retaliation; first of witnesses, then journalists and writers, then prosecutors and judges, then hostile businessmen and community leaders and eventually officials and politicians.
Then they'll start coming after the rest of us. Resistance may not exactly become futile, but it will soon be very dangerous.
