At this time of terrible loss at the Connecticut school, we reflect upon ways to prevent a reoccurrence of this horrible event. This is more than a gun issue, more than a societal issue, more than a mental health issue. The doors were locked, and the electronic security system was state-of-the-art. The only thing that could have prevented or mitigated this senseless violence would be an armed police guard at the school. Until we can find ways to re-educate the sick minds among society, we need to put an armed guard at all schools.
