I don't understand the way "active shooter" is being used in news stories relating to people being shot at an Arkansas night club.
Police said the shooting at Power Ultra Lounge was the result of a dispute among club-goers and not an active shooter or terror-related incident.
Apparently the actual police statement was:
We do NOT believe this incident was an active shooter or terror related incident. It appears to have been a dispute at a concert
What is the distinction between an "active shooter" and other shooters who are intentionally shooting people?
