This just in! Pedestrian on NYC street takes off outer shirt on a 90 degree day in Midtown!!!
Yea, I thought that was a bit odd also. Could indeed be the guy that did it but you cannot objectivly ignore a possible conclussion that he was just hot and taking off a shirt.
Now if it is a T-shirt over another T-shirt, well I guess there are people that dress like that. But, it definately would fit a pattern of someone trying to change their look.
With that bit of back and forth, we can only wait until they find the guy to see what is reality. You not wanting to jump to conclusions is exactly the right way to be.
