Having seen your profile I thought you would know that the ANO is quite specific on this subject.
You go on to say:
The reason you havbe had no problems with carriage of PPO's is that the whole idea is that they are discrete.
......and the armed police officers will also be discrete; that is the whole idea!

Although I agree with much that you say, you are mistaken in your knowledge of the APO's operating methods which are clearly defined in the DfT NASP
