AS I WAS driving along the motorway yesterday, I couldn’t help but admire the huge fence that has been erected in order to protect world leaders at the Nato conference.

However, after a couple of miles the fencing simply stoppedI don’t have any personal experience, but.

Surely a fence you can simply walk around to get to the other side is unlikely to stop any but the most simple-minded of terrorists – even supposing they lacked the ability to climb over or cut through it?
