For the purposes of tracking crime data, the FBI defines a "mass shooting" as any incident in which at least four people are murdered with a gun.
This will resolve to YES if a shooting in a school occurs in the United States with four or more fatal victims, before end of 2023, from the creation date of this question.
This will resolve to NO if no school shooting occurs in the US with four fatal victims or more.

Seems like the UNLV shooting being considered a "mass shooting" will come down to a patient in critical condition: https://twitter.com/LVMPD/status/1732545901737148527

I guess I did not specify “victims” enough. I want to clarify that the perpetrator shooting himself is not counted towards “victim” fatalities.

@GregoryGandy my understanding is that the police shooting the shooter does count as "being murdered with a gun" when it comes to the FBI tracking the stats.
If in this question dynd is not counting that then the quote about the FBI definition of mass shooting is entirely superfluous and confusing.

@zzlk The question is not about how the shooting is counted by the FBI. What is considered “murdered” is also irrelevant. Read the description again. The first paragraph is just an introduction on why the number four was chosen, instead of it being an arbitrary number. The definition that the market will result by is the amount of fatal victims, as clearly stated in the rest of the description.
As @GregoryGandy stated, at the time of writing, it looks like it will come down to whether the victim that is in critical condition will make it or not.





Just watching 10 minutes of network news coverage of this event make me want to go wash out all my sensory organs. Horrible Sensationalism.
