You can't go anywhere today without being on a security camera or in the presence of a phone camera. You can't make a fuss about having your picture taken without your consent as it's pretty much inevitable.
As long as these people aren't naked or doing something private etc. then let the dude continue.
I wouldn't be bothered unless they took like face shots or shots of my kids where they are easily identified. The pics looks kinda dope though. Homeboy at the end was wanting a nude pic session LOL
