I'll take a crack at it.
1. By labeling an American citizen an "enemy combatant", they can be imprisoned without trial indefinitely. No more due process in the courts.
See Brief for United States, Hamdi v. Rumsfeld,
542 U.S. 507 (2004). See also Brief for United
States, Rumsfeld v. Padilla, 542 U.S. 426 (2004).
See Timothy Lynch, Affront to Civil Liberties,
2. If you speak out against the government to advocate change, the government can take all your possessions.
Section 215 of PAI, which sunseted in 2005. I don't know whether it was renewed or not.
3. The Bush administration conspired with telecom companies to illegally wiretap American citizens' domestic communication without a warrant.
It's current news. Bush is seeking complete immunity for telecom companies who gave the Administration who knows how much of what on who knows who. I think he also wants immunity for him and his cronies for the illegal surveillance.

Scooter Libby took the fall for Cheney, was convicted and sentenced to prison. Bush commuted his sentence and will no doubt pardon him during his last few days in office.
5. They created National Security letters, which when a person is served with one, that person cannot even discuss that the search ever even took place, or they will be charged with a crime.
Excerpt from the Cato Institute investigation entitled "Power Surge":
The Bush administration has also championed the use of national security letters (NSLs). An NSL is another subpoena-like device that empowers federal agents to demand certain records from businesspeople.
Unlike search warrants, executive branch agents do not need to apply to judges for these devices. These letters also threaten citizens with jail should they tell anyone about the governments demand. When a constitutional challenge was brought against NSLs, Bushs lawyers argued that they were fully consistent with the Bill of Rights. The federal court was not persuaded. Federal Judge Victor Maerrero ruled that NSLs violated both the Fourth Amendment and the First Amendment.
NSLs violate the Fourth Amendment because they are written in tones sounding virtually as biblical commandments, thus making ithighly unlikely that an NSL recipient reasonablywould know that he may have a right to contest the NSL, and that a process to do so may exist through a judicial proceeding.
NSLs violate the First Amendment becausethey operate as an unconstitutional priorrestraint on speech.
6. Bush stated that he will not obey legislation if he doesn't want to. WTF???
He included that statement in an addendum when he signed the reauthorization of the Patriot Act in 2006

Apparently unsubstantiated
