That's what i find it unethical and even creepy at some point.In my opinion subject on photo should matter even in public places. Even if laws regard that fact, it's still wrong.
In that case, you can go to public beach, take photos of women in bikini (or maybe even topless) and claim it's my work and i can sell it. You can make profit out of somebody else and they don't have any rights? Actually i have seen an article 61 man took 13 year old girl's upskirt photo in Portland and laws couldn't do anything because she is in public place and wears underwear. WTF?!
In this case, you can make money out of somebody else's work. Nobody would look this low quality photos if it wasn't for upcoming movie which is not even finished. (Might have negative effect on movie) I think any photo about Suicide Squad comes out of WB should be illegal. That's not freedom, that's abusing it.
