"Just a bit of a personal rant about the quality of the modern-day officer-of-the-law and the dubious qualifications that are deemed to be sufficient to allow him to get involved with something about which he doesn't have a clue. In my opinion he then becomes more of a nuisance than a rubbernecking member of the public."
Yes, so we will train every response cop to be an expert in aviation accidents to the same level as the AAIB, and rail crashes too obviously, and response to COMAH sites, and non COMAH industrial accidents, CBRN (E) would need to be covered, and fires to the same standard as fire and rescue, because cops are normally there first, better add marine accidents to that list, oh what about hospital evacuation, oil refinery accidents, and fuel pumping stations too....shouldn't make basic training more than say five years.
That's why you have incident plans; you resource to a certain level first (because those six cars were probably all the available resources from that side of Leicestershire), as soon as the first unit gets there they give a SAD CHALET assessment to enable the response to be scaled up or down.
