One of my blokes was breathalysed by the police the other night, he was standing near his car after having driven home. His interior light was still on in the car and the cops asked if it was his car and they gave him the breath test. He passed the test even though he had partaken in a couple of beers. After a bit of discussion the question I have is this: If he was over the limit and drove home, was then approached by the police and legged it into his house and quaffed half a bottle of vodka what could the cops do to prove he was pis*ed at the time of driving?? I reckon that they would blood test him and then back track the results to prove he was drunk whilst driving? Probably an unlikely event, do any of you know the answer?? Might be one for you Manchester Monkey.
