Thursday evening, the CBS Evening News previewed a report to be broadcast this Sunday on the "60 Minutes" television show. Apparently, former NSA contractor and whistleblower Edward Snowden has more documents to release that are more damaging than the documents released so far.
The news report included U.S. government officials that are split about whether to grant Snowden amnesty to prevent the release of more documents (and additional damage from such releases), even though the Chinese and Russian probably already have those documents. Seems like a must-watch "60 Minutes" episode this Sunday.
All of this strongly suggests that the Chinese and Russian governments probably know more now about surveillance programs by the U.S. Government than U.S. citizens know.
