Justice Dept censors Supreme Court ruling

Becky sez, "The Justice Dept. blacked out (censored) the part of a Supreme Court decision that calls into question the willy-nilly use of the vague notion of 'domestic security' to suppress dissent. Oy."
Ostensibly, they would use their powers of censorship only to remove material that truly could jeopardize US operations. But in reality, what did they do? They blacked out a quotation from a Supreme Court decision:
"The danger to political dissent is acute where the Government attempts to act under so vague a concept as the power to protect 'domestic security.' Given the difficulty of defining the domestic security interest, the danger of abuse in acting to protect that interest becomes apparent."
The mind reels at such a blatant abuse of power (and at the sheer chutzpah of using national security as an excuse to censor a quotation about using national security as an excuse to stifle dissent).
