Police units that are unequipped for tactical operations may rely on a specialized SWAT team, which may have a dedicated sniper. Some police sniper operations begin with military assistance. Police snipers placed in vantage points, such as high buildings, can provide security for events. In one high-profile incident commonly referred to as "The Shot Seen Around the World" due to going viral online, Mike Plumb, a SWAT sniper in Columbus, Ohio, prevented a suicide by shooting a revolver out of the individual's hand, leaving him unharmed.
