Generally not. Unfortunately civil forfeiture is a thing. There are many stories, frankly 1 is more than enough, where people are driving with cash because either they, or their business partner, prefers/only-can-take cash. The police say you are a criminal intent on an illicit transaction. They seize your money. They hold the money on separate charges than you. If you lack the wherewithal to sue for your money back, you forfeit it. The money is then spend on things like guns, tanks, and margarita machines.
While this single link does not argue for all the expenditures, it does show the corruption in the system. https://www.forbes.com/sites/instituteforjustice/2014/06/05/...
