2004 was 13 years ago, mate. Sentences were generally much lower back then. The current starting point for a group/gang aggravated burglary where the occupants are at home is ten years after a trial.
I was just stating the minimum and how it was derived (which still applies), it is impossible to comment on the OPs without any facts.
AB is an odd one, it isn't just used for 'burglars'.
