I didn't even think about the balconies. I dunno about slow him down so much as cause more injuries/deaths and have a lot of people's worst imaginations while being on those balconies realized.
Could be. Not sure how many were still on the balconies at 3 A.M. FWIW, if this guy had done this at Midnight or around Midnight it would have been so much worse with many more dead and injured.
