Louise Ferguson notes that the terror attacks in Madrid used mobile phones as triggers, continuing the age-old tradition of new technology having both good and very bad unintended consequences.
"The law of unintended consequences is often referred to in favourable terms, with ordinary people finding exciting uses for new technologies. The deaths provoked by the unintended consequences of the mobile phone in Madrid this week demonstrate that technological advance, even involving seemingly harmless artifacts, can also have a dark side."
