He didn’t get “life”.
Yes what the gang did to the driver was of course unacceptable, and they should have been punished for it. But they didn’t set out to deliberately permanently injure the driver – and would you expect someone to get 30 years today for being in a gang which gave someone one blow to the head ? Every week we hear of worst acts of violence. 10 at a push 15 years would have been fair sentences imo.
And yes, he went over the wall at Wandsworth nick and went on to live a comfortable life for many years. But can you honestly say with certainty that the determination to spring him would have been there if he had received 10 instead of 30 years ?
As I said before, this wasn’t a case of “it’s a fair cop, I done all – so now I’ll serve my time”. The sentencing was criminal imo – and also in the eyes of much of the British public, which was always the major reason of his “celebrity status” And don’t forget, they never caught him – he came back on his own accord.
