No. It's a dumb thread. Here's why:
If a law is not being used for its actual intended purpose, the remedy is to enforce it so that it does get properly circumscribed. It is not to toss out the useful, valid law.
Furthermore, you are in no position to know whether or to what extent it is also being used FOR its intended and legitimate purpose.
BTW: I have already conceded that it has been used for drug cases, and I agree that this is a misuse and I am opposed to that use of the Patriot Act. That said, I still maintain that the PATRIOT Act is a terrific and valid tool for use against the evil scumbag terrorist shitheads that seek to harm us. But yes, even so, our vigilance is required to make sure its use is limited to that purpose and not abused to work on mere criminal investigations or prosecutions.
Not sure if you understand it was used for Terrorism (it's purpose)
less than a half of a percent in 2009. Try to imagine how small that is for a moment. When we have the raw numbers, we can in fact know the extent it is used for.
You seem to not also realize that all of this has already happens and continues to happen. It doesn't matter how much vigilance we have, us citizens have absolutely no power with this outside of having our representatives and senators repeal this bill. Considering both parties have no intention of giving up this power anytime soon, it should give you a good idea of how that will play out.
