^ agree...these look more like long lens private eye photos vs. traditional street photos; shot from close-in, B&W, grainy, AND with an interesting scene that tells a story. Not; "I got a picture of someone walking down the street that didn't know I was taking their picture".

Or this free e-book by Thomas Leuthard:
He talks about B&W vs. Color. He has some strong opinions that some don't agree with, but his results pretty impressive.
Lots of "rules" can be broken and still get results.
