In a public capacity, certainly. The DHS should work with other branches of government to ensure that the conversations of all public employees are recorded and sent to the public at large for review.
By having her conversations recorded and played back in Wal-Marts average citizens could report any suspicious activity she makes to a Wal-Mart manager. What if a Wal-Mart customer recognized someone she was meeting with as a terrorist in disguise. Or that someone had brought more than 2 oz of water to a meeting and that it might be a bomb.
These are important measures that she should be taking to ensure her freedom. Just like the government monitors our conversations at 655 Folsom to protect our freedom, we should monitor theirs to ensure their freedom. Government officials usually enjoy the most amount of freedom in a society, we know that terrorists hate us for our freedom and we know that they've attempted to destroy government buildings during 9/11, therefore the public should be on high alert to help government officials maintain their freedom by monitoring all their communications. It's really the least we can do to protect them from freedom hating terrorists.
Unless she's a terrorist herself, or doesn't love freedom I'm not sure why she would be trying to hide her conversations from us.
Not necessarily every single one, but generally, yes.
I think government officials should have virtually no privacy in their official lives. Unless someone is actually saying nuclear launch codes or passwords out loud, there is no reason for official conversations to be hidden from the public (I'm talking about people making decisions, not the rank-and-file civil servants).
In fact, I think the absurd level of privacy high government officials have today is extremely destructive and dangerous.
It is usually accepted that at the highest level of government conversations should be recorded, yes. If it wasn't for every conversation in the Oval Office being recorded and subsequently subpoenaed Nixon probably wouldn't have had to resign over Watergate.
Why should someone be forced to use one mode of communication when all of her written communication (memos, etc) is already on the record? This sounds silly.
