Look, I think it’s important to understand that these minimization procedures are taken very seriously, and all other agencies that are handling raw signals intelligence are essentially going to have to import these very complex oversight and compliance mechanisms that currently exist at the NSA.
Within the NSA, those are extremely strong and protective mechanisms. I think people should feel reassured that the rules cannot be violated—certainly not without it coming to the attention of oversight and compliance bodies. I am confident that all of the agencies in the U.S. intelligence community will discharge those very same obligations with the same level of diligence and rigor, adhering to both the spirit and the letter of the law.
