If you use Google, everything you do is stored in a database and all linked together. Anything from email to searches to maps, etc., this is all linked to your profile. Now the gov’t has issued a large subpoena for Google’s data:

With that data, the government can google everyone in it to easily find things they are interested in. Have you any relation with anti-war organizations? They can easily find you, the gov’t is already monitoring anti-war organizations. Even PETA is now monitored by the FBI. Ever emailed someone named Osama? Its actually a common name. Or maybe you support the left wing gov’ts being elected in Latin America. The U.S. has already backed a coup against Chavez, and you only need to look at what the U.S. has done in Latin America thruout the 20th century to know that they’ll probably be tracking that too.

You can help the situation by rejecting Google’s cookie in your browser, which is what Google uses to track you. But if you use any Google service that uses a login, then all your info is stored in their databases. Even if Google really lives up to their motto, “don’t be evil”, the government can subpoena Google’s database, and they have no such mantra they follow.
