Here’s the oath Snowden took when he went to work for the government:
Federal employees take the same oath of office as Congress, by which they swear to support and defend the Constitution of the United States of America.
“I, [name], do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I take this obligation freely, without any mental reservation or purpose of evasion; and that I will well and faithfully discharge the duties of the office on which I am about to enter. So help me God.” 5 U.S.C. §3331
In other words, he promised to:
“Support and defend the Constitution of the United States against all enemies, foreign and domestic…”
Seems to me you could make a strong case that Snowden actually acted in accordance with his oath, if you view the deeds of the domestic National Security Establishment as being inmical to the letter and spirit of the United States Constitution.
It is those who continue to justify and support the endless assaults on our Constitutionally-guaranteed liberties by the Security State who are the vile oath-breakers. At least, that’s the way I see it.
