School riots Milwaukee due to cell phones,
"...After a series of violent events at Bradley Tech High School where people used cell phones to get others involved in the fights, Milwaukee Public Schools is now heavily enforcing a ban on cell phones in schools.
MPS rules already tell students not to carry cell phones during the school day, but students often disregard those rules.
Superintendent William Andrekopolous also explained that if a student makes a call to someone outside the school and the situation threatens someone's safety, the student will be expelled.
Serious fights happened twice at Bradley Tech High School because people used cell phones to call in for help in those tussles.
Milwaukee County District Attorney John Chisholm explains that if a similar incident happens again at an MPS school, those involved will receive felony charges...."
I wonder what 'expelled' means anymore. When I was in high school, being expelled meant the end of your involvement with the public school system. It only happened to students age 16 and over (you could also drop out at age 16 under state law) and you were then on your own. I had several friends expelled (only one for taking a swing at a male teacher --- he missed) most often for truancy. If you were deemed 'incorrigible' under the age of 16, they sent you to "reform school" -- junior prison -- until you were 16.
I don't know how they handle this stuff today.
