Baston , old chap You are actually quite offensive in your remarks . I take it you speak from a long history of experience as a serving police officer , during which you encountered all manner of violent people and faced oodles of differnent weaponry.
Police officers in the main are not incompetent , the senior officers set over them and the policies and procedures they have to abide by most certainly are .
As for no go areas , you really do watch too much television .
Having worked for years as a police officer in London and Manchester I have yet to even hear of a no go area let alone avoid one .
Behave
Alternatively Joint eh special constabulary , Im sure you would clear the crime rate up in minutes few with your exceptionla knoweldge of policing matters
