The problem is that--so far--we don't have a good way to allow the acceptable kinds while also prohibiting the terrible kinds.

Imagine the police give an overwhelming list of false/non-existent evidence and testimony, so that the average (innocent) person would assume they're being deliberately framed by some power they are unable to fight, and that the only way to protect themselves and their loved ones is to buckle under.

Another example would be where police lie/deliberately-mislead a suspect about the consequences of a confession.
