Put these elements together: actual torture under our existing laws, the possibility of actual knowledge that the OLC opinions were phony, conduct outside the restrictions even of those opinions and a possible improper motive outside of legitimate national security concerns. That's a theory of criminal liability, and it has not yet been eliminated by the evidence. From a prosecutor's perspective, the stonewalling we have seen -- aggressive assertions of executive privilege, refusals to cooperate with inspectors general, cover stories that don't withstand scrutiny -- raises suspicions further.
