Closing Central Park would be pretty difficult to do. It's 2.5 miles long and about a half mile wide with over a hundred entrances. Most likely they contained a small area.
I've seen fireworks that can blow off your fingers, but this blew off the guy's foot. This was a lot more powerful than any firework. Probably a small IED.
