Well, hello? McFly? Are you really fucking dumb? By increasing the drinking age, all you're going to do is increase the number of under-agers drinking.

By raising the age threshold, he claims: "It is at least possible that those in their early and mid teens will not see drink as something they will soon be allowed to do so therefore they might as well start doing it surreptitiously now."
And it's utter bollocks. They'll see it as even more of a laugh to drink, since it's even more not allowed by the nanny state. What's even better is that he goes on to concede that this will not actually solve the problem, but in true "something must be done" and "won't somebody think of the children" fashion, he's prepared to fuck it all up.
Some kids are still going to get shit-faced on Buckfast, MD 20/20, Merrydown, and other such delightful beverages. Some are not. No amount of fannying around from a new labour think tank is going to change that.
