This all started years ago with the McDonalds shooting as well as a few disgruntled Post Office workers.
if we are going to trace the origins for mass murder events in the USA we need to back up to 1927 the Bath School Massecure.
the 55 year old Bath township unified school district school board treasurer , planted 2 explosive charges under the school 1 went off killing 38 and wounding 56 others , the second device didn't go off
a 3rd device planted in his own house killed hiw wife
he then assembled the school board in response and shot the case of TNT in his passenger foot well area of his truck killing most of the remaining school board members and him self
when you start studying actual mass killing/mass shooter events you start to see they hold fairly steady with the population
actual events however are clouded in recent years by how the media classifies them
and not the real definition , or the new 2013 definition
even by the 2013 definition reducing the number to 3 victims in a event not tied to other crime like drug or gang activity.
the media may have reported >300 mass shootings but the FBI only has 61 active shooter events for 2021 only 6 made mass
https://www.fbi.gov/file-repository/active-shooter-incidents-in-the-us-2021-052422.pdf/viewso yes you are being mislead by the media
there have been 4 including this one in 2023
2023 is a record breaking year the oldest mass shooter jumped twice this year 67 and 72 it had previously been 66
if you didn't hear about those they didn't fit the narrative the media is going for
in 2018 , 27 active shooter events , 10 of 27 appear to be mass death events 3 or more
https://www.fbi.gov/file-repository/active-shooter-incidents-in-the-us-2018-041019.pdf/view2019 it was 28 events 12 made mass killing status
https://www.fbi.gov/file-repository/active-shooter-incidents-in-the-us-2019-042820.pdf/viewin 2020 it was 40 events 5 make mass shooting
although the FBI reports contradict them selves the 2019 report stated 28 but the 2020 report states 2019 as having 30
not a huge gap but they don't publish these till well after the year is complete so it seems an odd discrepancy.
