LONDON LAWYER V GLASGOW COP

A London lawyer runs a stop sign and gets pulled over by a Glasgow copper.
He thinks that he is smarter than the cop because he is a lawyer from LONDON and is certain that he has a better education then any Jock cop. He decides to prove this to himself and have some fun at the Glasgow cops expense!!
Glasgow cop says, 'Licence and registration, please.'
London Lawyer says, 'What for?'
Glasgow cop says, 'Ye didnae come tae a complete stop at the stop sign.'
London Lawyer says, 'I slowed down and no one was coming.'
Glasgow cop says, 'Ye still didnae come tae a complete stop. Licence and registration, please.'
London Lawyer says, 'What's the difference?'
Glasgow cop says, 'The difference is, ye huvte come tae complete stop, that's the law. Licence and registration, please!'
London Lawyer says, 'If you can show me the legal difference between slow down and stop, I'll give you my licence and registration; and you give me the ticket. If not, you let me go and don't give me the ticket.'
Glasgow cop says, 'Sounds fair. Exit your vehicle, sir.'
The London Lawyer exits his vehicle.
The Glasgow cop takes out his baton and starts beating the pulp out of the lawyer and says, 'Now, dae ye want me tae stop, or just slow doon?'
