Louisville shooting live updates: 4 victims killed inside bank, 9 injured

The Gun Violence Archive defines a mass shooting as at least four people shot, not including the suspect. By their skewed math they have come up with "146 mass shootings committed in the US this year." This claim is absolutely preposterous.
First we need to recognize that one cannot compare apples to oranges, or to grapes. A universal standard definition needs to be reached. The Congressional Research Service defines Mass Shootings (MS) often include multiple-victim shooting incidents that occur in connection with some other crime. These may include felony-related shootings where both the victims and offenders may be involved in unlawful activities, such as organized crime, gang activity and drug deals. Domestic disputes are incidents where the majority of victims are members of the offender’s family, not random victims as are associated with "true" mass public shootings. Depending how the MS data is sliced, events associated with domestic violence and criminal activity make up 80 to 88 percent of mass shooting incidents in the U.S. with four or more fatally injured victims (Krouse, William J. and Daniel J. Richardson, Mass Murder with Firearms: Incidents and Victims, 1999–2013, Washington, D.C.: Congressional Research Service, R44126, 2015.).
Mass Public Shootings (MPS) are most commonly defined as follows:

The FBI (Federal Bureau of Investigation) defines a mass murderer as someone who kills four or more people in a single incident (not including himself) with no “cooling-off period” between the murders, typically in a single location. Randomness is one of the major hallmarks of a true mass shooting. If pro self-defense Americans are to be heard and understood while the anti-gun lunatics scream at the top of their voices, their must be a single definition with reliable statistics.
