why i say "life goes on" part 5

The investigation into Harley accident took almost a year. I knew we were doomed right off the bat. We were called to the accident sight one afternoon by Travis Green who was doing the investigation on the scene. Just shortly after we arrived we were going over some of the details of the accident that night and there were a couple of things that didn't make any since to me. First of all my Jonathon Martins(the boy who hit her own admittings he was going 52 mph on a road posted 35mph so i ask Travis if he was at least going to get a speeding ticket and he said no, he was only going 7 mph over the speed limit and i said no he was going 17mph over the the limit. Travis continued to tell me that the speed limit on that road was 45 and not 35 (all speed limit signs are posted 35mph and below) .Then he said words that will forever be stuck in my head, he said "one teenagers life has already been ruined, why ruin another one"? I knew we were in trouble. Also by Jonathons own admittings  he said he stopped because he had to pick his mirror up out of the road because when "hit the dog it broke his mirror".....ok call me crazy if you want too, but has anyone ever hit a dog that knocked off their drivers side mirror???? He said he didn't even know he hit her until Boz (harley's friend) came to see what the loud noise was (the sound of the collision) and realized harley's shoe was on the side of the road..he knew she had been hit and starting screaming "where is she, where is Harley"? Then Boz jumped off the side of the road into cudzo and searched for her.  How do you hit someone one not once, but twice and knock your drivers side mirror off your truck and not even know you hit them???? This was the craziness that we were faced with.  Anyway , when Travis said "one teenagers life has already been ruined, why ruin another one" I like to have went postal on him. I knew nothing would ever be done to Jonathon. I looked at Donnie and told him to get the car and get me out of there before i killed him(travis). I couldn't believe this was the way the police were thinking, and at the same time, i knew that if it had been me driving that night and would have killed someone, I would be under the jail. Would they be thinking this way if it was their daughter???  Back to the speed limit signs. To show you how dumb out justice system really is. On the police report the speed limit was said to be 45 on that road (even though as i said before it was posted 35 and below) I had to go to the road dept. and have a statement signed saying the speed limit was 35 and not 45. (The report never changed). These are the officers that we have working for us. Travis was later fired for unrelated reasons but rehired about 1yr later. There were facts that we went far out of our way to prove right or to prove them wrong during this investigation, but nothing was ever done about it. It is really sad that a grieving mother was having to do her own investigating on he death of her own daughter because the law would not do their job in fear of "ruining " a teenagers life.
