The idea
I'm not suggesting anything like 'life should mean life' or anything to that effect.
Currently if you commit 14 crimes in Britain, each with a certain servicable sentence you get a sentence on the judges calculations. Usually this would not be anything close to what the sentence would be if all the terms were added together.
Sentencing is concurrent so when you go to prison you serve sentences for all your crimes and convictions at the same time.
I suggest adopting American sentencing policy where you serve each sentence and conviction one after the other. When one sentence/conviction ends another begins.
Why is it important?
Each crime has a punishment instead of an umbrella punishment.
Obviously this would greatly act as a deterent.
I realise its unlikely to have action taken on, but it is a talking point.
