When it comes to the CT school tragedy last week the school thought they were safe with the person having to ring a bell to get into the school but apparently not. I think that to save people from tragedies like that for a person to get into a school they have to have a pass that they scan with photo ID on.... and only parents or guardians allowed in the school besides staff. I believe also that there should be at least two police officers at a school at all time to protects not only children but also the lovely people who work there. It is such a sad thing that happened to all those poor children and adults.
