It is a delicate balance security and rights. These people who claim their rights are being infringed upon will be the first ones to complain that the government failed them when they are at the funeral of a loved who died in a terrorist attack. When one person dies or thousands die, then its said to the government, "How come you didn't do enough?" The govt responds by saying, "You didn't give us the tools." So my question is one persons life worth the security of a nation? Or do we have to quantify that with a larger number of dead before we say we need better security and if some of our rights are infringed upon so be it? The average person going to work and raising a family is more concern about gas prices and food than security IMHO. They think about it but it's not in the forefront of their thinking.
My opinion, I do not have anything to hide from the government, I am not a criminal or a terrorist so if big brother is watching to make sure we are safe, then so be it. I am not worried. Also how bad are your rights being infringed currently? Is it affecting your daily routine in the least bit? Lets be honest here. Who is honestly getting up everyday and putting on the tin foil hat? Or are you going about your business? I can answer that, you are going about your business.
