Our system is by no means perfect, but it's a damn sight more justice orientated than the US, and involves a lot more common sense.
Our wonderful government wanted to adopt a cookie cutter sentencing system that is popular in parts of the US, pretty much every magistrate and most judges opposed it as it wouldn't allow for any common sense, and would often end up with either people getting off easier than now, much harder for simple crimes, and a much more complicated system (the idea is you have effectively a spreadsheet with crime + general factors = mandatory sentence, which is great until you realise it'll need hundreds of factors taken into account to even come close to the sort of factors that the judges already take into account).
