Since the Florida shooting, schools around the country have seen an uptick in threats, incidents of violence and false alarms reported in the media. A group that tracks such reports, the Educator’s School Safety Network, says an average of 70 incidents have occurred daily in the weeks since the Florida shooting, as compared to a more typical pace, of about 10 to 12 incidents a day. Hard to measure, though, is how many of these incidents represent an increase in false alarms, due in part to heightened vigilance, and how many reflect a new surge in truly dangerous threats.
