The burden of proof will have already been achieved the previous two offences, 3rd offence, out the back and shot. The US system is so expensive because they make it so.
Can you name one individual, who, under UK law, has had 3 custodial convictions quashed for 3 separate crimes?
no it won't be we've sent people to prison falsely before some times for decades, that's why you have to keep death row inmates alive for decades and let have so many appeals which have to be carried out under the highest specifications which costs millions per appeal.
it only takes 1 wrong conviction not all 3.
then you have to hold them, you can hold them like normal prisoners they'd ****ing tear the place apart as they have nothing to lose, the extra security is again very expensive.
what you're suggestions a hacked down system that will have many errors and mistrials and kill hundreds of people, the country would never stand for it and is no longer justice it'';s just a death squad hiding behind a pretence of a court.
after the first "shop lifter schedule for execution for stealing dvd" you'd be ****ed.
