So if you move the setting to London (where I think most of the police jargon comes from and Charlie gained his experience) and change the factory to Grunwicks near Wembley and the National Front to miners and other left wing protagonists then this is essentially what the Special Patrol Group did! So there are a few inaccuracies (probably born of memory fade) like, you didn't get a solicitor in the charge room (not custody suite until 1984) to see the staion sergeant (not custody officer until post PACE) until after charge. Like - teams are called reliefs. Like Storno Personal Radios were crap and you could only rely on the main set.
But ..... it caught the spirit of the times, the comaradery, the sheer crazy humour and raw bravery like no other book I've read. Come on Charlie - tell the bank to stick their security job and get back to writing about the early eighties (before PACE neutered the cops). Stop faffing about in a Northern facsimile town and tell us about Arbour Square (if thats the real Hotel Alpha/ Horses Arse).
