that one ranks right up there with the amendment that created a tax on income about a hundred years ago. The government promised that the rate would never rise above 2% for citizens.
I was in an Army Ranger Company in RVN. Six years after I got out, I moved from the St Louis area to SW Idaho. The Ranger Company started having reunions, and I got an Email updating me. When wifey and I went to the next one, I asked how they found me here more than twenty years later.
Answer: one of the guys went to work for a Federal Govt agency. He tells me, at the reunion, that he simply went to the NICS record system and looked to see the last address I had listed on a firearms purchase. I asked him how he could find my Email address, since it is not required. He just smiled; and said "I work for an agency that can access everything on everybody in the US, and most foreign countries...".
I would bet, given five minutes and your first and last name, he could give you complete details of your last dental visit.
