I always understood it was more than two. There were three victims today, but the councilwoman was not killed.
This from the web:
“Broadly speaking, the term refers to an incident involving multiple victims of gun violence, but there is no official set of criteria or definition for a mass shooting, according to criminology experts and FBI officials.”
Not all mass shootings are equal in my eyes.
Gang shootings usually have a single target with multiple wounded and killed.
What I think of as a mass shooting involves a lone nutjob who targets as many unarmed strangers as possible.
