Yes, it was a tangent, but you might be interested in a short review of Jeremy Scahill’s Dirty Wars: The World is a Battlefield:
‘Not long after he was elected president, Barack Obama arranged what senior US officials called “Terror Tuesdays”.
‘On the agenda were “kill lists” — names of individuals whose perceived threat to America’s security made them targets for assassination by unmanned drone attacks in Pakistan, Yemen, and Somalia.
‘The kill lists, scrutinised personally by Obama at the weekly meetings, were soon expanded to become what US journalist Jeremy Scahill, author of Dirty Wars, calls a form of “pre-crime” justice where individuals are considered fair game if they met certain life patterns of suspected terrorists.’
