In a statement released by the FBI on Monday, mass shootings increased 52.5% between 2020 and 2021 and 96.8% from 2017. For the period from 2017 to 2021, the data shows an “uptrend”.
The FBI defined an active sniper in its report as “one or more individuals who have been actively involved in killing or attempting to kill a person in a populated area”. When considering whether to include shootings in their reports, researchers look at incidents that have resulted in mass homicides in two or more places in public and are not the result of other crimes and appear to be spontaneous. And they see if the shooter is “organized to find victims.”
