They ARE!  Where have you been?  But they can't do it all at once...they have to take baby steps.  The first thing Bush tried to do in office (Feb '01) was get Miranda overturned.  He's been chipping away at your rights ever since, spying on you, reading your email, using satellites to track your movements, and people are winding up in Guantanamo Bay because they're dissenting.  CENSORSHIP IS REAL.  (Besides, they can't control ISPs and webservers that aren't US-based, but anyway...)
