I was quite struck by the way Snowden talks analytically, the same way I do. His sentence structures and logical processing were the same as mine. Snowden says that sometimes, to do the right thing, you have to go outside the law a little. No, I;ve never thought I could take the law into my own hands. But "the right thing" does go beyond the expectations of others.
Snowden says that US vulnerability results from a failure to connect the dots and recognize significance of publicly available information, not from not having the "dots".
There is a lot of discussion about the Snowdel email to the NSA on his concerns (Vox has an explanatory link) and if he has a lot of these emails as he says, why didn't he save them the way he saved material that leaked?
