Colin Powell speaks regularly to high-ranking U.S. officials, he knows a lot about what's going on in the government. And so he's a powerful person who merits transparency, just like any other powerful people do.

As always, imagine how great the press corps would be if it devoted 1/1000th the energy to dissecting non-sex political wrongdoing

No matter the specific techniques involved, historically mass surveillance has had several constant attributes. Initially, it is always the country’s dissidents and marginalized who bear the brunt of the surveillance, leading those who support the government or are merely apathetic to mistakenly believe they are immune. And history shows that the mere existence of a mass surveillance apparatus, regardless of how it is used, is in itself sufficient to stifle dissent. A citizenry that is aware of always being watched quickly becomes a compliant and fearful one.

When someone who wields political power does something you dislike or disagree with, it's incumbent upon you to object, criticize, and demand a different course. Those who refuse to do so are abdicating the most basic duty of citizenship and rendering themselves impotent.

Snowden has enough [sic] information to cause harm to the U.S. government in a single minute than any other person has ever had. The U.S. government should be on its knees every day begging that nothing happen to Snowden, because if something does happen to him, all the information will be revealed and it could be its worst nightmare.

Arming domestic police forces with paramilitary weaponry will ensure their systematic use even in the absence of a terrorist attack on US soil; they will simply find other, increasingly permissive uses for those weapons.

The many pro-surveillance advocates I have debated since Snowden blew the whistle have been quick to echo [Google CEO] Eric Schmidt's view that privacy is for people who have something to hide. But none of them would willingly give me the passwords to their email accounts, or allow video cameras in their homes.
