What nonsense! Let me translate: Holder wants relief from the pressure to prosecute Zimmerman, so he's shifting to a topic that has nothing to do with Zimmerman but that low-information people think has to do with Zimmerman. (Zimmerman was pinned down before he decided his life was on the line, and he had no route of escape.)
And, yes, I know Holder is also talking about investigating the Zimmerman matter. But "investigating" is code. As we saw with Benghazi, it means: We're hoping that if enough time passes, you'll forget about it.
This is all so thoroughly lame. But at the same time: It's a very powerful person speaking dishonestly and threateningly about the exercise of power. What a disgusting combination.
