Even before Milwaukee Public Schools as a whole launched a new effort to bar cell phones from schools this week, Bradley Tech High School officials were trying to do that.
“If it’s visible and it’s being used, we confiscate it,” Principal Ed Kovochich said Wednesday, the day MPS leaders, District Attorney John Chisholm and others came to the school to announce steps aimed at reducing violence, with a cell phone ban getting the most attention.
So how many students at that moment were carrying cell phones inside Bradley Tech?
Of 1,600 students in the school, Kovochich estimated, 1,500 had cell phones on them.
“But I’ll give you a buck for every one you see,” he added.
He didn’t need to pay up.
