Kenneth Roth (head of Human Rights Watch) and Salil Shetty (head of Amnesty International) make an appeal to President Obama in the New York Times to pardon Snowden on merit, and for the public good. It's all part of a much larger campaign.
In his biography on Twitter, Mr. Snowden says: “I used to work for the government. Now I work for the public.” That should not be something that gets you locked up for a lifetime or compels you to live in exile. The president has an opportunity to correct that injustice. It’s time to pardon Mr. Snowden and bring him home, not to face the music but to work for the security and privacy of us all.
