I think I saw him, too, as I was walking back from lunch at around 2:45ish. He had one of those gasoline spray cans like the guy who set fire to that lady in a Brooklyn elevator back in December. I walked past him thinking he was a sanitation worker spraying one of the cans for bugs, but then I saw all the other cans already on fire.
The fire department came and put them out shortly afterward. No word on whether the guy was caught.
New York City, in case you didn't know already, is crazy.
