When the states started making Noknock warrants legal was when the system started downhill. Despite the Justice department's arguments it does violate the 4th Ammendment. A little considered argument against noknock is that it also violates the 6th Ammendment because the police will never tell you who told them that you had drugs in the house.

If they do find anything they get to keep all of your possessions, so naturally they are bound to "find" something - even if they have to bring it with them.
