Honest guys Im not police bashing but its easy to blame someone else
The police cant effect the outcome of a trial, what a lot of tosh.
The Police choose to overlook traffic violations all the time admittedly not in fatal accidents. They also tend to be the only people allowed on the scene to collect evidence. What evidence is included is therefore down to their skill and integrity.
Ned in a saxo, dead girl, case closed!
A judge made a decision on the evidence presented to them in this case by the "expert" police crash investigators report. This report actually conflicted with two eye witness statements. But the jury was told crash investigator evidence was "crucial" in the judges summing up.
So yes it was the police who convicted him. Then the Sheriff "punished" him
