How can you ensure the footage is kept "at the school" (as if that was sufficiently limiting the exposure of the footage)? Who has physical access? Is the surveillance system cloud based? How is the school's security? Are her superiors legally allowed to watch the footage to evaluate performance? Could those overbearing aggressive parents eventually demand access to the footage, and worsen the whole problem? Are the childrens' parents aware of the consequences of the cameras? That every tiny little move in the formative phase of their children's lifes is recorded for all eternity, and that data generally tends to leak, and all kinds of entities want access? It is data. People were surprised when 1980s-era USENET forum posts where made accessible a few years ago. Back then it was unfathomable that this data would be searchable and accessible or even relevant, but it was. Same with our data now: it will be analyzed in ways we cannot even imagine. I am stunned by how quickly surveillance spreads.
