hope they don't try to blame you. My friend's dad had exact same situation where he was rear-ended by an out of state police. He talked to local cop and said something about sudden stopping in middle of traffic and they wrote him a ticket and told him to fix his own car. He stopped because all the traffic stopped and he couldn't argue. Only choice he had was to hire a lawyer and nobody wanted to take the case. there are many good cops but some aren't so "good".Got rear ended Tuesday night, Lucky for me it was an undercover police officer driving a city car. I had just made my second payment, 2000 miles!
