JohnnyOnTheSpot, NYC Edition

I was in NYC yesterday. I have never seen such a visible PD presence in lower Manhattan (pre bombing). I spotted two mobile command centers (battery park and just north of Wall St). Counter terrorism marked cars with license plate scanners working up and down the streets, and an NYPD helicopter that was flying a grid pattern over city at about 4000ft agl. There were uniformed officers all over in groups of two and four, all wearing the counter terrorism back patch, and lots of K9 units deployed.
