The words of Justice Brandeis echo down thru the decades...via McJoan at Kos. And Christy's keepin' us on our toes, what a patriot looks like, over at firedoglake. FISA matters, precisely because of Brandeis' words:
If the government becomes a law breaker, it breeds contempt for law; it invites every man to become a law unto himself; it invites anarchy. To declare that in the administration of the criminal law the end justifies the means 'to declare that the government may commit crimes in order to secure the conviction of a private criminal' would bring terrible retribution.
[From dissenting opinion in Olmstead vs. United States, in which the court upheld the use of wiretaps in a case involving an investigation of bootlegging. Brandeis strongly defended the individual right to privacy from government intrusion.] -Louis D. Brandeis, 1928
