I'm not convinced that these are the guys based upon the photos and other info that has been released so far. The guy with the white cap is carrying a dark backpack that seems to blend in with his dark jacket and as a result, I can't tell from the NY Post photos (as well as the other photos that were all over the internet yesterday) whether or not he still has the backpack in later photos. Also, if he planted the backpack with the bomb in it sometime prior to 12:30 pm, then what are the odds that the backback would remain in the same spot unmolested for over three hours until the bombs went off? The area was crawling with uniformed and plain clothed LEO as well as private security and petty thieves.
With that said, there were reports late yesterday afternoon about a video of a dark-skinned guy wearing a black jacket, white hoodie, and cap turned backwards, dropping a backpack in the area where the second bomb exploded across from Saks Fifth Avenue. Directly to the left of the two guys in the photo there is another guy who meets the description of the guy in the alleged video.
I think he still has the backpack on in the second photo. It’s just underexposed.
