Just going back to the principles, I think it is better to set the maximum and then allow a lot of latitude for the courts to determine how serious the offence actually was. We at John Howard, along with many other organizations, have problems with mandatory minimums generally, because they do not allow the judiciary to impose a penalty that may well be proportionate to the seriousness of the offence and the degree of responsibility of the offender if it is under what is set as the mandatory minimum. So I like the idea in all cases that there be no mandatory minimum set.
In terms of how you would justify a mandatory minimum for an offence of mischief that is less serious than the one you've just described, I think it raises some serious concerns of parity amongst the Criminal Code provisions.
