A wake-up call
The teacher's attack on a pupil using a dumb-bell was an incident waiting to happen. That the boy survived is good - but the next one might not. As it exists, our education system results in conflict and stress all round. A classroom incident which results in a trial for attempted murder should be a wake-up call for the powers that be.
