From the press reports the jury were convinced by the evidence of the defence 'expert'. If spindrift's info is correct this person has no special qualifications in traffic, driving or crash investigation - he is a motor mechanic. The prosecutors should have challenged him and ripped him to shreds, but as often happens they lack any specialist knowledge and unless they have already lined up a counter expert they let this sort of crap happen.
remind me of the [ame="http://en.wikipedia.org/wiki/West_Memphis_Three"]West Memphis Three[/ame].
(they got convicted by an 'expert' in the occult claiming that those three black metalist are murderer because they renounced "satan").
