An active-shooter drill Friday morning at River Park Hospital helped local emergency agencies prepare themselves for a mad gunman unleashing an unprovoked attack in this community.“It helps us get on the same page,” said McMinnville Police Chief Bryan Denton of the drill involving local law enforcement and emergency agencies at Saint Thomas River Park Hospital. “We can assess our response through drills like these.”The drill began just after 9 a.m. when 911 dispatched police to the hospital, telling them there was a man with a gun who had opened fire inside the facility. Dispatchers were quick to warn the fictitious shooting was a drill to avoid a War of the Worlds-type incident where scanner listeners might believe the armed assault was real.As emergency responders took their positions around the hospital, a tactical team made its way into the building and began sweeping the hospital, looking for the gunman.
