CNN: Pentagon announces that 4200 military policy are going to be deployed to New Orleans. That's good. Why wasn't that done yesterday?
Patience.
It was probably being done two days ago. You just don't snap your fingers and magically make all the military people appear somewhere. Plans have to be made where to deploy them. This involves assesing where they will most be needed which first includes a damage assesment. Transportation has to be arranged, supplies have to be procured, etc. etc. etc. Don't fall for the MSM spin on this.
I suspect the Pentagon wouldn't announce it unless it was already done and they're en route. (I know those from Massachusetts are.)
