In this setting, as well as in most places in open carry states, when the system sees a gun in hand, “BRANDISHED Firearm” setting is on. When this mode is on the system sends an alert anytime a weapon is seen in hands, no matter who it is. The idea is that the system gives risk information, and IF there is a gun in the hands of SRO or anyone (with good intentions or bad), it’s a risk (to have a gun in hand), indication of potential incident, and security should know about it.
