Understandable, but I doubt much bullying is happening during class time, where I feel that having cellphones put away would be the most beneficial. Several times I've been asked to put my cellphones in pouches that set off alarms when opened during small comedy shows/concerts, I feel that might be an alright solution to in class device lock down. Then when the class is over phone can come out.

In terms of bullying I think that's more a failure of the education system that these students don't have someone to turn to, in the faculty, to deal with it. It sucks because I couldn't imagine what bullying is like now in the digital age. I always felt that teachers and admins never got enough power to deal with severe bullying without blow back from parents.
