I will up that story one. A hard working father who was an up and coming musician traveling from state to state doing any and every job he could get was pulled over. Back story--His music group would sell t-shirts, music cassettes, posters..anything they could make money selling after their shows. They were pulled over on their way back to Texas by a good local sheriff who spotted their nice SUV with wheels. No drugs were found but of course they had cash and merchandise gear. The officer asked if the cash was from drugs and they replied multiple times no. The officer informed them he'd not arrest them or tow their vehicle if they'd sign the paperwork giving up the cash (he didn't care for the t-shirts, hats and music lol). They refused to sign the paperwork so he promptly read them their rights, arrested them all and called for a tow. The local sheriff had a nice little scam going where he'd shake down travelers between Louisiana and Texas border. They hired an attorney to fight the illegal seizure and won their case but lost money as they had to hire an attorney--as they weren't reimbursed for their expenses! Sometimes the law designed to stop the real drug dealers is used to target innocent travelers. FYI--the same sheriff seized money from a family on their way to bury a family member where it made the national news.
On a personal note, I had an officer attempt this same crap pulling me over where I did not consent to a search. Very unpleasant experience when you're a law abiding citizen who works hard and play hard...listening to Ramsey and Suzy about paying cash and not carrying debt...yeah right!! LOL Just don't get pulled over with emergency cash in case you break down cut off from the real world.
