Presumably his case is that it's unjust to financially penalise the responsible many for the actions of an irresponsible few.
I once read somewhere that 70% of the adult UK population drinks alcohol. That raw figure obviously includes everybody from the tanked-up and aggressive thugs and vandals in city centres to the old ladies who have a Baileys on Christmas afternoon and every point between. However, there are vastly many more of the latter than the former. So, if education works, the point stands: why screw the sensible majority as a means of getting at a senseless minority?
