Curious. Are there laws in place that require schools to have bullet-proof glass? Metal detectors at the entrances? Security camera inside and outside? Full-time camera monitoring? Other security related measures in and around the school, including the parking lot? Certain type entrance door? Did the town discuss these measures with the public before the tragedy? If so, then perhaps the school/town were negligent. If not, then I can't see how this lawsuit will prevail in a court of law. That said, I cannot imagine the pain these parents (who lost their children) carry with them.
