Cold hard cash is the way lots of police agencies fund themselves using asset forfeiture in make believe crimes. They confiscate, refuse to charge, give no receipts, and you're sh*t outta luck in getting it back. It's all done under the guise of "suspicion" and the local small town governments say tough luck. I guess you can call that a business.
One way to get around that is to trust banks, or at least credit unions, and use plastic for all your large transactions. Beyond that, go with god and good luck.
All the best,
