RICO is a prime example that is clearly malevolently misused by prosecutors to coerce behavior. Bad Law for good reasons. Defense attorneys do the same thing on a different front. They have the defendant routinely plead Not Guilty regardless of whether or not he did the deed or not. The reasoning here is to delay the process for as long as possible in the hopes of wearing down the prosecution to get a better deal for the client.
Witnesses die, move, disappear.
Evidence gets lost. Other things get more important for the state to pursue. The wealthy client gets probation and the poor bastard with no money gets 10 years. The lawyers benefit and we pay a pretty heavy price - the cheapening, denigration and eventual degradation of our justice system. The Law has become so cumbersome it lends itself to Legal Extortion.
