Geeks beware when taking the tube
Just read this disturbing article from a journalist and computer enthusiast who was arrested on the London Underground as a suspected terrorist for using a laptop and, among other things, *not* looking at the police officers as he entered the station and looking carefully at the steps as he walked down.
All in all, very scary. If you must take the Underground, please remember not to run on to trains to avoid being shot repeatedly in the head and try and fight your urge crack open your notebook computer lest you be arrested as a suspected terrorist.
In fact, it's probably best not to wear a jacket or carry a rucksack.The biggest danger in taking the Tube increasingly seems not to come from terrorists but from those who are supposed to be protecting us.
