You are right. Don't say anything if you don't have to. Just show them the card Peggy Hall has developed. Personally, I avoid talking to the police simply because they are NOT a friend. They are a stranger, who work under a quota system. They are 'leaned-on' to bring money into the city coffers. This is why ticket, fines, and fees are a big revenue generating source for cities. Personally, if I still got booted after providing the card, I wouldn't argue, but I would ask for the individual's contact information and his manager's contact information and the legal department. If I had to stand outside to get the information, I'd do that. Once I received that information, the fun starts. This is when they'll have to 'lawyer-up' and I'm costing them thousands of dollars to respond to my complaint letter and Cease-and-Desist Pre-suit letter. You never want the police involved. Avoid the police and avoid the Courts. Mediation and arbitration is how you want to burn money in through their pockets.
