They also abused their authority to persecute William Binney and Tom Drake - both acted to defend the constitution against those that defied it (all of whom took the same oath).
Then there was the telcom scandal under Bush - when it was revealed that both the government AND telcom companies (AT&T) were in blatant violation of the law for years, they not only changed the law to excuse themselves, they changed it retroactively!

Its not only a double standard anymore, I think its much worse.
