Let me play "resident curmudgeon" here if I may. We would have been CANED at my English high school (second oldest in England, founded in 1553) for this. Detention seems way too lenient!
and
a) let's bring back school uniforms
b) let's allow teachers to clip some student behind the back of the head for smarta$$ comments in class
c) the parents of said offenders should get the detention
d) let's give the principal a raise for having principles!!!!
