It has expanded the power and ability the government has to intervene in the lives of its citizens. This is true. But it is HOW the power is utilized that makes a difference on trampling on people's rights. Just because the government has more power, does not instantly mean your rights are violated. The Patriot Act is a good tool in undermining terrorism and terrorist related crimes, if utilized properly.
If there have been any abuses up to this point they have been, as far as i know, under the radar. Just because they have not happened yet does not mean they won't, however. You're right on this. With power, comes responsibility -- something that is not flawless with anyone. There will be idiots who abuse this power, but I am sure they realize that lawyers, media, interest groups, etc will be all over their asses -- something that keeps the extreme minority of idiot power-abusers in check
A substantial part of the patriot act gives the gov power to regulate and investigate any part of the internet they think may, even in the slightest bit, relate to terrorism. The gov't would only pursue such actions if they knew they could have a viable case. Now, with that said, in a lot of cases on the internet, evidence can be very time sensitive. A federal judge could issue a search warrant. I think this process is still in the works, because it will sunset in 2005.
This is one instance of it working... but naturally you're going to hear about any minor "success" resulting from the act, and will hear nothing about how it is giving the government greater power in your life.True, but the Patriot Act is relatively new, and still being 'tested' out. In the future, I think there will be more criminal indictments of people who are comitting and promoting terrorist acts.
