spring-peeper said:Such safeguards are not possible. We have never had real safeguards against invasion of privacy.
But we can create sanctions for the invasion.
The exclusionary rule for purposes of over zealous criminal investogators in the US wouldn't punish those officers but it would prohibit them from benefiting from the violation by exclusing any eviednce so gathered from admission in court (under most circumstances - a criminal may not freely lie relying on the fact that evidence previously ruled inadmissible cannot be used. Rather, previously exclused evidence may be introduced in rebuttal to impeach a statement from a witness)
However, criminal investigation is backward looking - meaning it seeks to discover who committed a crime, catch them and punish them for it. Natonal security is forward looking in that it seeks to prevent an act from occuring in the future. As such, in the US the 4th amendment, which prohibits "unreasonable" warantless searches is variable according to the interests being served. What is unreasonable for purposes of criminal investigation may not be for national security reasons. The problem though is this - - if those conducting the searches for national security purposes breach the reasonableness requirement - what is the sanction? An exclusionary rule doesn't work. So, TAE - what do you think?
