I know it's tough when a pig is grilling you, but the best thing to do is just keep your mouth shut. Cops are trained to turn up the heat and indimidation and get people to incriminate themselves. You don't have to answer any questions for the cop at all. If you open your mouth you should be asking the pig the questions. Ask him if you are under arrest or further detained. If not then leave. Once a cop has given you a ticket, their time with you is finished unless they are detaining you or arresting you. No further investigation is warrented unless you give them reason for it.
