I am a privacy advocate, I like to have my privacy, its a matter of principle, Bush did not go through the proper channells to eavesdrop. He circumvented the court system under the guise of national security. Also, his claim is that he has this power from the executive war powers he was given after 9/11 but do you think anyone in congress with the exception of the 5 or 6 he told would think that this is the type of power we have given him. If he went through the proper channels then I would not be as mad as I am. However, he went into my "house" without a warrant and searched around in it. For those that have nothing to hide, it doesn't matter, would you enjoy it if I went into your house or on your computer without your permission or without a warrant saying that I can and started looking around, I could sleep in your bed and play with your cat; he illegally obtained permission using a power which it was never meant for.
I believe in Ben Franklin: "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety."
It strikes home to the point, that the government wants to watch its citizens, hell the FBI is trying to tap the internet and watch everybody, so you could eventually have a society where what you see and what you do is controlled by the government. I don't want that.
