Agree . But the unmasking was one of the tools that was used for illegal surveillance of US citizens. They would use unmasking as a surveillance tool without applying for a FISA warrant. I also mentioned unmasking because that was the issue that came up in the monitoring of Trump and his people. And it was the issue with Susan Rice, and the documents released from Whitehouse staff assigned to the National Security Counsel-- Ellis and Cohen-Watnick--- which were released to Nunez-- they dealt with conversations that were unmasked. Cohen-Watnick made an extensive search of documents pertaining to US citizens but only provided the Trump related information which dealt with unmasking. This will be investigated by Congress as they have been mentioning it and the whole area of illegal surveillance which has gone on since the Patriot Act was passed.
