Glendale's cyber-nosey schools

[Commentary] Glendale (CA) school officials have hired a firm to monitor the social media postings of their students, apparently in an effort to learn about potentially dangerous behavior such as cyberbullying, suicidal thoughts, sexual harassment or drug use. The firm might turn up some troubling stuff, and even if it doesn't, knowing that Big Schoolmarm is watching might persuade some teenagers to show a little more caution about what they broadcast online, which would not be a bad outcome. But neither of these potential benefits outweighs the creepy thought that school officials are intruding into students' off-campus lives and spying on conversations that are, in the vast majority of cases, none of their business.
