Active Harmer

An Active Harmer is an individual(s) actively engaged in killing or attempting to kill people in a confined and populated space; in most cases, active harmers use firearm(s) with no apparent pattern or method as to how they choose their victims. Active harmer situations evolve quickly and there is no way to anticipate their course. Active harmer situations can be over within 10 to 15 minutes. For this reason, it is important that you are prepared to take the actions necessary to protect yourself.
