Just like that zone of lawlessness inside of peoples minds that the pesky 5th amendment creates, think of all the criminals going free because we can't force them to incriminate themselves! This is a situation that the DOJ and other alphabet agencies have brought upon themselves by thinking they are above the law in the first place.
Or the Fourth Amendment. Or the Second. Or the First.
The situation is clear. We must take care to ban this subversive document now. For the children! For the Feds! For great justice!
