I agree it is important to stop terrorist attacks. They've one end in mind. The destruction of the west, all religions but their own, and in the end, their own dominance of the world.
I also agree the monitoring of enemy communications is important. In this day and time with the onset of computer technology and throw away cell phones it is a difficult task. In respect to, Remember we are the government, that's debatable. There are too many uneducated, uninformed and gullible voters voting and too many politicians that regard their desires and greed more than the good of the country and it's people.
I also agree that too often important intelligence methods are revealed to the public for our own good. Sometimes it is 'leaked' by our own government officials. This I believe borders on treason.
Where our opinions differ greatly is in your statement:
I hear a lot of people that believe their civil rights are being trampled, as you do. However, not a single one has presented evidence that their rights ave been violated in any way. The slippery slope argument is a logic flaw.
I used to believe also that the Patriot Act was a necessity, that we needed it to fight terrorism. That was until I learned more about it. They have gone way overboard.
The 'Patriot Act' was not even read by those that voted it into law before they voted. It is full of instances that contradict our Constitution. Dem. congressman john conyers even admits he (they) don't read bills before they vote on them.
You state "that not one single person has presented evidence that their rights have been violated in any way".
The Patriot Act gives so much power to the Feds that violate our Constitutional rights that [if one is investigated by the feds] and they speak about it, whether it is to the press, their lawyer, their wife or even to a judge, then they've commited a Felony. That's even IF they find out they've been or are being investigated because the Act gives Feds the right to write their own search warrants. This is just one instance that is atrocious.
I'll link below one or two YouTubes for you to look at. While I do not endorse Napolitanos' ending remarks, he might to be too far off base. I say this because we must never show our tail in the face of the enemy. This only shows weakness. (You'll know what I mean by that when you hear who he endorses. The endorsee has a plan of immediate withdrawal and that is the one big problem I have with him.) Take a few minutes and watch at least the first one.
