Funny. I'd expect that if I was working for an organization supposedly doing "good", which turned out to use extremely questionable methods, I would not feel depressed due to the public reaction. I would feel incensed at the thought of having been lied to and betrayed by my hierarchy. The reactions expressed in the article are more along the line of "politicians should come to the bat for us".
I can understand the feeling. Let me extend to them the same sympathy I have for former Stasi personnel, other Five Eyes SIGINT members and all the other people who think 1984 is an instruction manual. Because next year, you'll lobby for installing cameras in all private homes, in case the owner is a terrorist. And why not? You're already playing digital peeping Tom, might as well go all the way. Think of the terrorists. War is peace. Freedom is slavery.
