Just about everything we've seen about the insides of the NSA have come from only one source. Snowden was only employed there for 3 months, and has publicly stated that his primary reason for seeking employment there was specifically to gather information on NSA surveillance systems[1] - in order words, his opinions on the NSA were solidified before he joined. To top it off, Snowden is not available for interview.
I'm not even saying you're required to believe him. I do, however, think an insider's perspective has been sadly lacking from most of the conversation that's been going on. I don't expect journalists to have a complete understanding of all of the details regarding these programs and systems that have been leaked - they've never worked with them.
So, lorendsr, thank you for your contribution. Don't let the flat out negative comments get to you. I hope your post encourages others with a background in the NSA to share what parts of their experience that they can. Everyone else, please take advantage of this opportunity to ask questions, gain any insight that you can and don't just dismiss him outright.
