I like to use cash, and I keep a tally sheet and receipts with me when I travel, along with any withdrawal slips pertaining to the money. I can prove to a penny where it came from, where it was spent, on what, and it will equate to what is left.
But I get the impression that's not enough. As soon as they see cash, it's theirs.
And the thing is, I have plenty more in the bank. So if I am stopped and any cash or items are seized, the first thing I'm going to do is call my attorney and go about my business until I have sued the jurisdiction, the officer(s), and anyone else connected to the seizure back into the stone age.
I retired young after a successful career. Lots of tattoos. Gold Rolex, long hair, under 50 - I am an unscrupulous officer's wet dream. But I am sober, intelligent and law abiding. I never break the law and my driving record is spotless because of it. Pull me over and you're hunting, because you didn't see me weave.
Bring it.
And for those of you who are ready to say, "F you - you're rich", or whatever - spare me. I am exactly the kind of citizen who will eventually bring this kind of thing to a halt. I can afford to take it the Supreme Court. And I will do so with a relentless determination.
The police to me are a threatening force. If I need them, I'll go ahead and call. Otherwise, mind your own business and we'll be fine. So far in 47 years I have never needed them. And I know to a certainty I don't need them violating my rights.
