Looking at this political story from a programming perspective... What software out there can help me accept as input millions of photographs, with timestamps, locations, angles and such, and generate as output a coherent time line of each individual in each photograph so we can identify the copycat bombers that will be occurring in the following years? Surly machine learning software could be made to find a person in one image from a different image based on analysis of the configuration and color value of the person's clothing alone.

It's George Orwellian, but it will be created one way or another. Is there some software that can help achieve this goal?
