Arrived back from the channel islands with my passport for revenue protection purposes only into a busy airport and all I needed to get into the UK from the large hall where I freely mingled with international arrivals was a wee bit of paper with my name. i.e. the boarding card which they barely glanced at. The one that without scanned you could happily knock up on a laptop.
There was *nothing* to prevent a rendezvous with anyone else, giving him/her my document and entering through the arrivals hall with my passport. Big airport, lots of cameras but nothing to stop me in real time making a swap.
Is it REALLY that slack?
PS Journos if you're reading it's Gatwick South. Have a go. What a joke.
