NotifyNYC Twittered yesterday, "On Wed Aug 11, btwn 2PM-12AM a mock emergency response will be filmed in the vicinity of Washington Sq Park. NYPD will be onsite." Will the NYPD be on site to lend assistance or to make sure ticked off people don't headbutt PA's? Anyway, if you take pictures, share them with us by tagging them "gothamist" on Flickr or emailing them to photos@gothamist.com!
