Regarding the Aug. 16 front-page article “Audit: NSA repeatedly broke privacy rules”:

In defending its mistakes, the National Security Agency (NSA) said that the number is insignificant, but we don’t have a complete picture of how many mistakes were made as the audit only encompassed information from a limited number of agency offices. Additionally, the NSA said that the people who work at the agency are human and make mistakes.

That’s not good enough. That is why the NSA surveillance practice should be compliant with international legal standards that protect people from unlawful surveillance. Compliance would involve setting up a system to ensure that mistakes are identified and corrected before someone’s rights have been violated.
