When Congress wants to do something particularly objectionable, they tend give it a fine-sounding name. The PATRIOT Act is perhaps the best-known example. The legislation had been drafted well before 9/11 but was going nowhere. Then the 9/11 attacks gave it a new lease on life. Politicians exploited the surge in patriotism following the attack to reintroduce the bill and call it the PATRIOT Act. To oppose it at that time was, by design, to seem unpatriotic.
At the time, 62 Democrats voted against the Act. On the Republican side there were only three no votes: former Rep. Bob Ney (R-OH), former Rep. Butch Otter (R-ID), and myself.
The abuses of the Constitution in the PATRIOT Act do not need to be fully recounted here, but Presidents Bush and Obama both claimed authority based on it to gut the Fourth Amendment. The PATRIOT Act ushered in the era of warrantless wiretapping, monitoring of our Internet behavior, watering down of probable cause, and much more. After the revelations by whistleblower Edward Snowden, we know how the NSA viewed constitutional restraints on surveillance of American people during the PATRIOT Act period.
After several re-authorizations of the PATRIOT Act, including some cosmetic reforms, Congress last October unveiled the USA FREEDOM Act. This was advertised as the first wholesale PATRIOT Act Reform bill. In fact, the House version was watered down to the point of meaninglessness and the Senate version was not much better. The final straw was the bill's extension of key elements of the PATRIOT Act until 2017.
