The lawyer for Thomas Towle, the driver responsible for running down and killing six teenagers at Mildura, argued that it was unproven that Towle's driving with his son on his lap contributed to the accident. He additionally insisted that eyewitness claims to the effect that Towle was speeding were speculative.
I am not in a position to disagree with this claim since I wasn't privy to the evidence. However, it would seem to me that that lawyers are hell bent on wrecking every prosecution and short-circuiting all attempts to punish offenders. The suggestion that in doing so they are contributing anything useful to society in the way of improved justice are similarly unproven and even more speculative. The fact that their chief motive appears to be money and prestige greatly increases that suspicion.
