Link to this because that's not what I'm seeing but mass shooting is changed by who is calling it that and what they choose to classify as a mass shooting.
The FBI defines an active shooter as an individual actively engaged in killing or attempting to kill people in a populated area, but the definition of mass shooting is less clear.

What is a mass shooting?
The term “mass shooting” can refer to firearm-related events with various outcomes depending on which definition is being used.
A 2020 article from the
National Institute of Justice Journal notes the challenges that arise from the lack of a single definition of the term “mass shooting.” Its authors claim that research is “hampered by a lack of agreement on definitions of critical terms, such as ‘mass shootings’ and ‘mass murders,’ and by the absence of consistent sources of data on mass shootings.”
Further, they note that “The federal criminal code lacks a distinct mass shooting offense; this may help explain why researchers use different terminology, or types of criminal offense, in their analyses of the same phenomenon.”
The Department of Justice, for example, shared a 2013 analysis of mass shootings that defines them as “any incident in which at least four people are murdered with a gun.”
News reports on the number of mass shootings in the US are likely to reference the Gun Violence Archive, a nonprofit that
defines a mass shooting as an event with a “minimum of four victims shot, either injured or killed, not including any shooter who may also have been killed or injured in the incident.” Many media outlets — such as Reuters, CNN, and the Wall Street Journal — reference this definition of mass shooting. According to that tally, the US has experienced nearly 400 mass shootings so far this year.
