Car accident in my neighborhood?

2 days ago there was a car accident in my hood( I call it this becuase the police are in here once every week or two) and the car pooled up in a drive way backed up hit there 700 dollar brick mail box left then hit another 700 brick mailbox going about 45MPH and ran in there yard but then left, two people hoped in there cars and another called the police. Then when they got to the car end of the street he turned around cause they surrounded him and the lady left and ran and the police cuaght her. When the two deputies and state trooper arrived they only gave him tickets and towed the car away. Then the trooper called the other guy about his mailbox and said nothing about them leaving the scene told them he walked up to the guys door and told him about the incident. The police officer lied to the guy at the other house cause he was on vacation. I was wondering if the officer should have put the man an woman in jail thanks. We are probably moving this summer. 10 points for B/A
