There is nothing "controversial" about this law; it's simply the state enforcement of preexisting Federal law. Anyone who thinks there is reason for an "uproar" doesn't know how to read, or, in Holder's case, hasn't read it at all.
He goofed up. He should have taken an hour to read the ****ing thing, especially when one considers the significance of the national dialog currently taking place in regards to this bill.
Ten freaking pages. Took me a little over an hour to read it. If he's going to speak authoritatively about a bill, he ought to read it.

Do your ****ing jobs.
