I think its the fact that the fight was one on one, so he would have probably just shot that one guy and split. To say that a mass shooting was prevented is stretching it at least a bit.
Just my take.
I understand, but what constitutes “mass”? I think a gunman with a loaded revolver on a school bus could create a “mass” murder. How many people need to die before it’s a “mass” shooting?
I think some people are trying to distract others with semantics because it’s easier than debating the issue.
