Has to make you wonder though, how he got them out of Dubai.
Either the authorities knew about it and let it go on to the UK to get him on a smuggling charge rather than possession,
Or whoever was on the x-ray machine was doing something else (like looking at Facebook or Whatsapp perhaps?)
Not like it doesn't happen as you pass through, let's be honest. I once went through and counted how many passed through after me before the officer on duty actually looked back at the screen. Six went by before there were eyes on screen again. I imagine it's not much different for the hold baggage, human factor is always there
And yes I did report it and you all know what reply there was....
