I disagree. He has stated 'The Law' as it is written. The 'maybe' comes in to how a Police Officer or Magistrate may interpret that Law and how the behaviour of someone may influence the on the spot judgement of a Police Officer (who are generally ignorant of many aspects of the aforementioned Law).
By the way he is a Master 7th Degree Black Belt (I looked it up). For £50 I will not pass on your details to him.
