Judy Keen, writing in USA Today reports that schools “across the USA are cracking down on students whose cellphones disrupt classes and make it easier to cheat.

Last Monday, “the 222 public schools” in Milwaukee enforced “a ban prompted by fights that escalated into brawls when students used cellphones to summon family members and outsiders” wrote Keen. “It’s a mess,” says Ed Kovochich, principal of Bradley Tech High School. He broke up a fight last month that involved a non-student carrying a pistol who arrived after getting text messages from students.

Under the new policy, Kovochich says, “If you use it, we take it.”
