Some of the fundamental changes to Americans' legal rights by the Bush administration and the USA Patriot Act following the 9/11 terror attacks:

Freedom of Association:
Government may monitor religious and political institutions without suspecting criminal activity to assist terror investigation.

Freedom of Information:
Government has closed once-public immigration hearings, has secretly detained hundreds of people without charges, and has encouraged bureaucrats to resist public records requests.

Freedom of Speech:
Government may prosecute librarians or keepers of any other records if they tell anyone that the government subpoenaed information related to a terror investigation.

Right to Legal Representation:
Government may monitor federal prison jailhouse conversations between attorneys and clients, and deny lawyers to Americans accused of crimes.

Freedom From Unreasonable Searches:
Government may search and seize Americans' papers and effects without probable cause to assist terror investigation.

Right to a Speedy and Public Trial:
Government may jail Americans indefinitely without a trial.

Right to Liberty:
Americans may be jailed without being charged or being able to confront witnesses against them.
