To this day no one in my family knows that I was the one who called the police to give them a detailed route of my brothers trips to his sister in laws house, she lives 50 miles away from us.
I explained the whole deal, that I knew my brother was driving with my nephew in the car while he was drunk (well, not drunk, topped up is a more apt phrase)
That I was sure my brother drove better drunk than 'sober' at that time.
They followed him, let him pass his son over to his sister in law,(I am so glad I explianed) then picked him up for drunk driving, he spent a night in the cells then was free to drive home.
Two months later in court he was banned for 12 months and had a £180 fine. He died before the ban ended. From alcohol related diseases. he was over double the UK limit while he drove his son 50 miles on the motorway in rush hour.
