Matthew Balas and Karen Osler, park rangers for the U.S. Army Corps of Engineers Pittsburgh District, shoot inert spray at Kyle Toms, who played the role of a disorderly visitor who attacked them during a training scenario at Crooked Creek Lake in Ford City, Pennsylvania, June 15, 2021, as part of a five-day Visitor Assistance course. District rangers who complete the course earn their park ranger badge and citation authority to enforce Title 36, which covers rules and regulations on federally owned parks and forests among other properties.
