I'm not denying what you are saying I'm just keen to see a report on interference on VHF Comms by a standard hand held mobile phone device. Always reminds me of the fact you aren't supposed to use them at petrol filling stations either and there's not been a scrap of proof that they are a source of concern. It's complete over-reaction.
Let's face it, you're trusted to evacuate a plane load of people but you CANNOT be trusted to take a yoghurt through security. I liked the line about threatening passengers with watching the take off from the air bridge, there's a few flights where I wish that had been done......
