Not got away with it yet, the CPS have not ruled out Appealing against the JP's decision. I for one hope that they do appeal and are successfull in the appeal.
Drink Driving is one of the lowest things that a person can do. Everybody has a choice and Gregan's was to go out and have a few beers the night before, in the full knowledge he had a long(ish) trip to make the morning after. He made that choice and then made the Choice to drive the morning after again in the full knowledge that he could still be over the limit.
IMHO he deserves to be banned for 6 Months, that might teach him a lesson. He only has to look at his team mates and players from other clubs to see the devistation drink driving can cause. Nobody should ever get away with it.
I am a firm believer that the limit should be 0. Everybody has been or knows somebody who has been effected by the actions of a drink driver.
The choice is easy don't drink or have a pint and risk ruining somebodys life/family.
