As I previously posted I know that so many killers deserve the death penalty or worse - I just don't have sufficient confidence in our police& judicial system
I lived near Guildford at the time of the IRA bombing and can assure you that 99% of the population wanted the 4 & the Birmingham 6 strung up
I also lived in Saudi where it was claimed the death sentence was only applied to those that had freely confessed in court - I leave you to consider what persuaded them to confess - and I can assure you it wasn't their conscience
With the B6 and G4 though they would never even get to court these days, back then the police were happy to fit people up with the view that they needed to gain or regain public confidence and they had to deliver "A body", if they struggled to actually find the culprit then they'd happily frame someone else who they knew or thought was guilty of other things and had got away with them.
The mindset appeared to be one of they were still getting justice for their past crimes that they'd got away with and no doubt the true culprit would in turn get caught for something else at some point that they may or may not have done so eventually would get locked up
Ah yes the good old days when coppers worked on "Nous" and the public trusted them

Nowadays they need evidence including forensics to 100% prove they are guilty and then hope the CPS allow the case to proceed, and then you have flaky juries letting people off because they had a tough childhood etc, oh and seemingly nobody now trusts the police or any authority because we have all woken up to the fact we were lied to big time on too many occasions
