Corrupt Police in Danvers, MA

For 10 years I have been complaining about the street in front of my house. I have 4 young kids and am married. In front of the house are single lanes that travel in either direction.

So, a car stopped seeing a red light down the end of the street and let my wife leave our driveway. There was a line of traffic down the street behind this car . We have 3 witnesses that gave statements, stating they saw a car traveling on the wrong side of the road cutting around traffic. When my wife pulled out she was hit by this car, totaling our vehicle.

I showed up roughly 15 mins after. The man on the wrong side of the road was not sited, and told me my “wife cut him off”. So, I flipped, and yelled A-Lot! The female police officer on scene (Suzanne Tibbetts) did not like it. She lost ALL witness statements, given a report that my wife was at fault and drawn a diagram that shows my street being two lanes. It clearly is not. The chief has defered all questions about the accident to her. He won’t help.

Who do I turn to now??????? Do they answer to NO ONE???
This is more of an illegal system, than a legal system.
Anyone got any ideas?
