In some cases, our use of cellphone cameras has the potential to liberate us when directed at the state, subjecting the powerful and privileged to forms of accountability that they’re not used to. That’s been made plain by the significant role of cellphone video in the movement against police brutality

But as we surveil each other in profoundly coercive ways, we also risk — as is often the case with informal forms of power — replicating the coercive power of the state itself. Surveillance disciplines our behavior, as any minority who’s passed through a security checkpoint in America can tell you in detail. It creates certain behaviors by design, most notably compliance, the willingness to do anything to avoid being hurt.

Once you accept that, certain things become clear. Your methods of checking have to be really quick. They have to be habitual, automatic. They can’t be cognitively expensive. And those who teach media literacy have to be conscious of this trade-off between depth and efficacy and act accordingly.
