On the one hand I commend him for exposing the extent to which American's communications are being monitored outside of what I consider to be the bounds of the constitution (no unreasonable search, etc). On the other hand, information about what the US is doing to other countries is a very delicate matter. True, we like to think of ourselves as the good guys who don't spy on our allies but, the reality might be that all countries are doing it. Certainly the Russians and the Chinese are.
My hope is that we will have some clarity and limitations on US spying respecting our constitution. Let's not forget that most of the people working at the NSA believe that they are doing the right thing to protect our country, but let's also not forget that power corrupts and absolute power corrupts absolutely,
