Pleb gate

Why shouldn't you trust a man with a basket on the front of his bike? Can he not be trusted to ride safely with it strapped to his handlbars? Is he going to steal it? Going to ride into a lamp post and damage it?

I find myself baffled by this question.

What I find peculiar about this whole affair is that no-one seems to question the right of a public servant (aka a PC) to refuse to open a gate to a cabinet minister, simply because he wanted to go through on his bike, rather than in a ministerial car. Even worse, he was instructed to use the pavement - has the law changed and we haven't been told aobut it?
