Just as the State will destroy DNA evidence that can exonerate prisoners already put to death - to prevent "undermining of the death penalty system", drones rain down down terror on largely innocent populations and bystanders - in the name of the war on terror, now the NSA is seeking to persecute Snowden for espionage, theft and conversion of Government property (data) - data which revealed that the NSA is doing exactly those things on as large a scale as their technology allows.
Justice, liberty, privacy, peace and security are but fuel for the State's burning ambition for supremacy.
