A Pennsylvania school district has canceled an active-shooter training event over concerns raised about "violent, homophobic and anti-Muslim" social media posts by the company conducting it.
More than 260 parents had registered for the event planned by the North Allegheny School District.
The event was intended to show parents the type of security training staffers receive. It was canceled after some parents raised concerns about Pittsburgh-based contractor INPAX, which has worked with the district for years. The parents cited posts they called "inappropriate."
