@layman,
The Supreme Court wrote: "Alternative sanctions of a perjury prosecution, administrative discipline, contempt, or a civil suit are not likely to fill the gap...self-scrutiny is a lofty ideal, but its exaltation reaches new heights if we expect a District Attorney to prosecute himself or his associates for well meaning violations of the search and seizure clause during a raid the District Attorney or his associates have ordered."

This 1978 case just held that,
in addition to every other available remedy, the evidence must be thrown out.
Even before this case was decided, a cop lying on a search warrant application could be:
1. Convicted of perjury
2. Held in contempt for attempting to perpetrate a fraud on the court and have his sorry ass taken straight to jail
3. Be bankrupted in a suit for violation of a citizen's civil rights, and, of course,
4. Disciplined internally by the relevant agency.
In these circumstances, I expect ALL FOUR of those "alternative remedies" to be pursued, know what I'm sayin?
