The MSM coverage isn't really bad. You have to understand that this situation is simply too large, too widespread, too complicated, to say much of anything that isn't so narrowly focused, parochial, that it contradicts the situation somewhere else. Or, going the other way, so generally applicable to this huge situation that it is little more than a string of banalities. That and the MSM is saddled with spoon feeding people with the attention span of a gnat.

It is a big situation that can't be meaningfully explained in two minutes.

A decent place to start:

But everyone is going to have to accept that you are going to have to dig and get information about it one piece at a time. Then again, if you're willing to wait a few years, I'm sure someone will write a book that will put everything in one spot for easy study.
