I have mixed feeling about this. On the one hand, as you will find in the article, it risks infringing free speech and guarantees against unreasonable searches and seizures.
On the other it had been used to catch a few bad guys.
Still there is the case of a Strip Club in San Diego where political corruption was the issue and they used the Patriot act to listen into conversations via On Star to gain convictions.
BTW they never had a warrant, and it held up on a slew convictions.
Senate moves Patriot Act toward extension - FoxNews.com
Squeezed against a deadline, the Senate late Wednesday moved past a standoff over a four-year extension of the anti-terror Patriot Act before part of it expire.
An agreement to hold a test vote early Thursday was the first progress all week toward resolving an impasse between Senate Majority Leader Harry Reid and tea party favorite Rand Paul, R-Ky., before three provisions of the act expire at midnight Thursday. Just before he closed the Senate on Wednesday night, Reid said there likely would be votes on amendments to the extension.
That could go a long way toward meeting Paul's demand that Reid make good on a promise earlier this year to hold a full debate on proposed changes to the post-9/11 law, which empowers the government to find terrorists on American soil. Paul and other civil libertarians of both parties say the Patriot Act should be reconsidered or repealed outright because it risks infringing free speech and guarantees against unreasonable searches and seizures
