Yes, we do. As little as possible. But what we've gotten over the years instead is corrupt and/or incompetent government drones who did not do their jobs. As a result and is as so typical with government, they then made even more laws that were never fully enforced. Lather, rinse, repeat.
I really don't know the answer to this aside from the unlikely sight of the lifeless bodies of the corrupt hanging as examples from DC lamp posts.
§ 4. Misprision of felonyWhoever, having knowledge of the actual commission of a felony cognizable by a court of the United States, conceals and does not as soon as possible make known the same to some judge or other person in civil or military authority under the United States, shall be fined under this title or imprisoned not more than three years, or both.
I don’t know. It seems on the street, these people are basically gamblers. The Madoff scandal indicates a need for serious regulation. The ‘little as possible ‘ regulation is what allowed Madoff, Wachovia, Goldman -all the bad actors to fly under the radar for so long essentially bankrupting this nation.
