From the BBC:
A key Islamic rights group is demanding an immediate inquiry after six Muslim imams were removed from a US flight.
The six men were taken off the US Airways flight, bound to Phoenix from Minneapolis, after a passenger reported "suspicious activity" to cabin crew.
Look, the people who intend to blow up planes aren't going to be the ones who stand up to pray before take off. Al Qaeda types won't spend months plotting an attack only to have it foiled because they chose a flight that conflicts with evening prayers.
