If we trusted them to adequately safeguard our information, and not to misuse it, then none of this would be an issue. But they've broken trust many times over and once that horse has bolted, you can't just close the stable door and expect people to just trust you again - especially not when you keep getting caught with your hand in the cookie jar, get caught lying about it or using smoke and mirrors to sidestep the consequences and then coming back and saying don't worry, not only can we be trusted with the cookie jar, but we must be the ones safeguarding you from the cookies because they make you fat. So it's for the good of everyone. Meanwhile, they're just sitting their eating the cookies. It's always a land grab for more cookies.
You wouldn't trust your six year old with that kind of behavior, you certainly shouldn't trust a Government agency that acts the same way.
I absolutely agree
