I do like to argue. With FR, I get all the arguing I need or want.
This particular rule is not my biggest concern with the Patriot Act anyhow. There are some other search provisions that do truly offend the 4th Amendment. But I do think this starts getting close to the line. Here is my thinking:
If we all agree that it is reasonable for the Government to seek information on all cash purchases in excess of $10,000. What if they want to make it $1,000, do you have a problem with that? What about ALL cash transactions? What if they say all cash transactions over $10,000 require the seller to obtain a photo of the purchasor? Where does it stop? I am 100% for fighting terrorism and criminal behavior. What I see is solution which is not going to stop terrorism, but opens the door to futher monitoring of non-criminal tranactions by citizens. Also, in addition to those with an ulterior motive in spending cash there are many people who just plain like their privacy.
