Bruce Schneier is the man. He's a really good, solid voice on current security. I'm 3/4 through his most recent book and there is not a moment reading it when i don't say, holy shit! that is so stupidly logical!

He's rather even handed when it comes to security decisions, he calls the current administration on what they've done right and what they've done wrong. (although there are cases when the wrong greatly outnumbers the right)

At any rate, here's a good example from his blog (of which i have become a daily reader)

He's just really good at analyzing security, and enumerating the trade offs. In the end, that's what it all comes down to. It's great to see such a rational voice getting good press these days. Those voices are the ones that will turn this mess around.

An even more exhaustive list of the things Schneier can do.
