It's the first day of what's been billed as a trial for the record: those accused in the January 2015 attacks, which started with a bloodbath at satirical weekly Charlie Hebdo, while a separate attacker targeted a policewoman and a kosher supermarket. They ended with shootouts that killed the Kouachi brothers and Amedy Coulibaly and world leaders converging on Paris for a massive "Je suis Charlie" march. So who are the 14 now on trial: minor players or major accomplices? Could the same overlapping networks that jumped between al Qaeda and the IS group back in 2015 strike today?
