Can I sell street photos?

If a Paparazzo can take a picture of anyone he likes and sell it to highest bidder, then I expect we can too. It's not a legal opinion in any way, but every day we see pictures of famous people, taken without their consent, which have been used for commercial gain.

I recently saw a talk by UK photographer Tom Wood. You may know his book 'All Zones Off Peak'.

The boy in the red and white shirt saw himself (in the image below) in the Tate Art Gallery many years later. He has since grown up and obviously bears no resemblance to the kid in the picture. However, the guy got his lawyers involved and now Tom is not allowed to show or sell the picture. He did not share details about this, but I remain curious. I guess he could have fought it, but as Bukowski says "it is cheaper to plead guilty"

Any source for this? A quick Google search turned up nothing.
