I wish I had your confidence lookout.
Me too Grahame, they all drop their guard at some point though, its noticing it that matters.
There are way too many unresolved 'issues' in this case, but perhaps some are not as important as they would seem, we tend to look for fault once we form opinions of right and wrong. The police look for a collar, a good nick, personal reputation, its not all about putting the bad guys away. Most cops see it as a game, once someone is nicked its all about getting a successful prosecution, the investigation is secondary. If they (cops) believe in the accuseds' guilt then it must be so. Don't believe in the custody sergeant making an independent charging judgement either, or the CPS looking at matters overall. All part of the same body - they look after each other.
The Courts (Magistrates/Judges) primarily - support the police or the prosecution - the accused has no voice, they are treated as guilty before trial, which is why they are treated like criminals from the outset - innocent until proven guilty is a lie, it means nothing, watch any court case, the accused has no rights at all, everything they say is questioned, whereas everything a cop say is accepted as the truth. Don't get me wrong, most folk in court are there for the right reason, that doesn't make the system flawless though.
