KNIA/KRLS listeners in Knoxville have noticed Iowa State Patrol vehicles coming in-and-out of the VA Campus. It turns out that troopers are in the area as part of a training exercise. More than a dozen Iowa State Patrol vehicles were on the north side of the campus on Wednesday afternoon. A patrolman on site tells KNIA/KRLS News that they’ve been using a building on the north side for an active shooter exercise since the beginning of the week.
