By Christine Spolar | KFF Health News PITTSBURGH — A false alarm that a gunman was roaming one Catholic high school and then another in March 2023 touched off frightening evacuations and a robust police response in the city. It also prompted the diocese to rethink what constitutes a model learning environment. Months after hundreds of students were met by SWAT teams, the Catholic Diocese of Pittsburgh began forming its own armed police force. Wendell Hissrich, a former safety director for the city and career FBI unit chief, was hired that year to form a department to safeguard 39 Catholic schools as well as dozens of churches in the region.
