SIB? Are you nuts, you do want the ecrime investigate with some semblance of order don’t you. You wouldn’t let the SIB investigate missing T bags.I like Sean (Endeavour) Evans, the coxwain but am intrigued as to his actual rank. He is on tea swilling terms with the Captain and appears to be completely running the whole fiasco; please will someone enlighten me as to his actual naval rank/rating? Finally, in my limited military experience gained many years ago, surely the Special Investigation Branch (SIB) would have regarded the whole shebang as their fiefdom and while thankful the armed forces are subordinate to the civil power in this democracy of ours, do no accept that the civilian police would have had jurisdiction aboard a highly classified warship over the death of one individual. Alright I know this is a story but I like accuracy; there are always plenty of ex servicemen who could put the producers right without jeapodising security.
