My wife and I still spend a lot of nights in CA. We have work there despite our new legal residency in NV. I've often said - "it doesn't hurt to go" meaning bug out to our NV property when things are "just weird." I felt like that when Zimmerman's verdict came out - watched it from the safety of my NV bug out. I have felt that way a few times. The video above is why you don't wait. Its hard to watch, its a cell phone video so not all that good, but you will get the idea.
By the way this is how the "good people" of oakland treat someone in a car accident.
