Security surveillance cameras have become generally accepted and the intended use is pretty obvious. Honest people don’t have a problem with those cameras.
Some random dude with a camera, using his “power of silence”, or playing passive-aggressive with people, and throwing off a creepy vib with an attitude WILL rightfully bother some people. Especially when his intentions are unknown.
One day, maybe some dude exercising his right not to be filmed will hold up his hand in front of the camera lens to block his being filmed. I can envision a scenario where the cameraman then “accidentally” bumps into his hand and his camera accidentally gets shoved into the back of his skull.
When the police arrive after the tussle, witnesses will say that the creepy cameraman deliberately walked into and pushed the other guy which resulted in the camera getting planted in his face.

Not something I would do, but I know people.
