It could mean that, but I think we both know that's not what he was trying to say, being that all the lead up to this is the crime was being allowed to happen rampantly and nothing was being done about it, and by the fact that he didn't argue that in response, but as usual tried to make a shift. It could just as easily mean the local law enforcement was in fact doing the job and didn't need the military to be doing law enforcement activities.
I don't know either way, I'm not in DC, and don't really trust the soundbites they're giving us. Just pointing out that the data doesn't necessarily show "change is in the air, boss". Just seems like more grandstanding from my perspective.
