I know how the system woks mate, my response was to Dave's assertion that this wipe stain will be out on the quiet in 5 years. He won't be.
I dont know whether Doyle will be eligible for the 40% served scheme that labour brought in recently so ignoring that, he will certainly do 50% to 66% in gaol, then the remainder on licence. Not sure this cockwomble will be able to see his nose clean for those licensable years having been in clink for 10-12 years. He'll come out an even angrier man and will spend the rest of his life bouncing between institutions. Sadly other people will get hurt in the process.
