Look out behind you!

So Mr Tony got hit on the back in the Commons today? Just as well it wasn't anthrax or ricin some will say.

If anything this shows putting up that glass screen at a cost of nearly £3m is utterly futile; especially since the men arrested were guests of a Labour peer and were therefore sitting in the section reserved for Parliamentarians' guests - and which isn't separated by a glass screen.

I predict the usual hysteria and outcry will ensure with the authorities will draw the conclusion that glass screens should be rolled out to cover all sections above the Chamber.

But if security was beefed up at the entrance, where X-ray machines and body searches abound, then presumably such an incident would be less likely.

Of course, that would be the obvious solution. But as with identity cards (see below) I doubt that will happen...
