While it sounds crazy at first hand to bet real money on terror incidents, like the DARPA futures market suggest, it can be a much more exact tool to predict terror. Instead it has been furiously critizised in the media.
It is very unsatisfying that this remedy which could have been a very progressive indicator of the likeliness of terror events has found such an end. Tim Oren is elaborating more deeply on the economic viability, but I feel it's just wrongly sold to the public. A better story about and a nicer marketing could have avoided the crash now.
