I cannot imagine they will want to realize one day that you, their father, their President, got in the way of investigating the previous administration for War Crimes. 

Yes, during your campaign you assured voters that you would "look ahead, not to the past" on this issue.  We know that you have kept to many of your campaign promises, even ones that many progressives overlooked, or assumed you would not keep.  Many of us are trying to give you the benefit of the doubt on many matters, knowing that often you have been smarter, and a better big-picture, long-view chess player than we are.

But on this matter, we also know that in your heart and as matter of legal and Constitutional principle, you know how torture has undermined our country's value in the world.  You are engaging in a new kind of foreign relations model, but on this one huge issue, you are wrong.

Perhaps Spain's inquiries will trigger domestic investigations and/or prosecutions.  To paraphrase Constitutional expert Jonathan Turley about investigations:  "They would be the shortest investigations on record.  We already have the smoking gun."  All you need to do is get out of the way of investigations, and quit protecting the Bush Administration.  It is a pivotal moment in the narrative of the United States in regard to The Rule of Law. 

Please, do  not abdicate your responsibily in this matter.  Or one day your daughters will find it necessary to defend your decision to their daughters, and it will not be a good conversation.
