As Edward Snowden wrote, the Executive should lead the charge to;
"Appeal for a return to sanity, Constitutional policy, and the rule of law rather than men."
First and foremost President Obama should,
1. "[C]all for a special committee to review [..] interception programs"
President Obama should,
2. "[R]epudiate the dangerous "State Secrets" privilege," (or at least call for a required & recorded "In camera" validation, to be publicly released, in not more than 10yrs, in any and all validated cases)
3. "[B]egin a tradition for all Presidents forthwith to demonstrate their respect for the law by appointing a special investigator to review the policies of their years in office for any wrongdoing."
"There can be no faith in government if our highest offices are excused from scrutiny."
