If there is one thing I've learned on the Internet it's that reading the article is not a prerequisite for having a strong reaction and commenting on it.
I'm not sure actually reading the PCLOB report is very informative. I certainly don't have the context to understand it fully, and of course a lot of it is blacked out. Reading these sorts of disosures and putting them into context requires a LOT of domain knowledge that I don't have.
Wyden being pissed about it is a decent sign that it's something to be worried about though, he's spent a lot of time on this stuff.
