A recent question to the Mayor of London:
‘In light of the recent tragic death of Gary Mason in Sutton, should we be concerned by the recent statement from a leading barrister that “excuses of not seeing cyclists seem to be too readily accepted by the police and the CPS”?’
Written answer from the Mayor
No. The police take all fatal collisions investigations seriously. In every fatal collision investigation the police gather all the available evidence so that if there is any culpability by a third party, then the police would be in a good position to mount an effective prosecution.
The following is not a cycling case, but it's fairly typically of the treatment of vulnerable road users by the justice system. Look at what happened when Kristina Sporbeck was run down and killed in Knightsbridge. Witnesses said the driver Ali Megerisi was driving at "high speed", "It was like when you have a police car chasing someone. What struck me as well as the speed was the sound of the engine going into another gear." The driver was charged with careless driving but the case was dropped. The coroner described the case as "simply a tragic accident".
Does this sound like effective prosecution to you? If you're the family of the victim in a case like this you will likely be left with a deep sense of injustice that the killer didn't even need to appear in court to account for his actions.
