Can the police set up speed traps in private property?
I was recently given a ticket for speeding. I heard that the police cannot set up speed traps on private property (the police officer was set up in a school parking lot), and I want to know if this is true. I am taking the ticket to court to plead my case (I'm not disputing the actual ticket iteslf), and I was wondering if the court runs off of what is written on the ticket or what the offense actually was. The ticket was written for going 5mph over the speed limit, but in reality I was goin more like 10mph over and I was tailgating. In court, do I talk about the 5mph over or the 10 and the tailgating?
