Dekortage writes: "Although claiming to be miles away at the time, Jason Jones and his brother were nonetheless arrested for murder earlier this year. Now, thanks to travel data linked to Jason's subway pass, the brothers have been released on bond. Notably, Jason had initially offered his MetroCard to police as a way to check his alibi, but they did not; it did not happen until much later, when his lawyers got the records (PDF) from the transit authority. The judge has now expressed doubt in the accuracy of the lead witness, quoting Heraclitus: "The river now flowing by is not the same river that passed by yesterday." Sometimes all this 'big brother' stuff can actually help you out."
