Yes, that is a difficult question, as it turns out, because a lot of mandatory minimum sentences have been struck down on the theory that if they have disproportion.... I do not agree with this reasoning, but what the court has said is that if they were disproportionate for some offenders, then they're cruel and unusual punishment, forgetting the notion that there are a lot of problems with judicial discretion as well. In my mind, there's a lot to be said for mandatory minimum sentences for offences which Parliament has described as extremely important.
