The characters I'm dealing with are police officers for a very small constabulary (small enough to have neither a chief inspector, nor a DCI; the highest ranking member of the service is an inspector) in the West Country. One of the detectives has been shot by one of the sergeants, and is near death from the wounds. The sergeant that did the shooting has fled, as has the other detective, leaving just the wounded officer, and the inspector. There is a mobile phone in their possession, and the inspector needs to ring emergency services, but he can't ring the station directly, because he has reason to suspect that most, if not all of his officers are corrupt. Without knowing the direct line to the next nearest constabulary, how would he go about dialling 999 without just getting his own dispatch, or would it go to a generalised dispatch for the region/county?
Second question: The scope of the issues facing the small village is much greater than originally thought, to the point that most of the residents have been involved in a years-long conspiracy resulting in several score deaths. It's a small village, of the "one road in, one road out" variety, but very spread out. What would be the process taken by law enforcement in the event that the entire village was completely off its nut, and killing thy neighbour was (in this very small scope) an acceptable thing to do. Hypothetical is fine, since I'm fairly certain this sort of thing only ever happens in the films.
ETA: I realise that a lot of this is contradictory from fact, but I'm trying to balance badly-researched canon and believable situations, which is why I'm here. :)
