One thing that cell phone cameras are helpful with is the recording of strangers doing horrible (and conversely, wonderful) things to people and thinking they can get away with it, consequence-free. For example, this video taken by a woman named Azmina (she's using only her first name, due to concerns for her safety, because that's what it's like being a woman online in 2016) of a very intoxicated man who took it upon himself to randomly punch the crotch of a woman he found attractive and just keep walking, nbd. But she wasn't cool with that; she chased him down, and forced him to apologize, on camera.
