My grandson attends this school and mass during school hours. This mass is open to the public while the children are attending. There has been at least one incident this week where an individual who was known to the public as a potential danger to children who attended and was asked to leave. This puts our children at risk for potential danger and violence. Measures should be put in place for their safety and security, just as there are at the school itself. The public is not allowed to wander into the school and engage our children, why would we we allow that in their mass time?
