Nashville school shooter’s identity may make them an exceptionally rare perpetrator

According to all recorded data, the US epidemic of mass shootings are committed overwhelmingly by cis males

In the immediate aftermath of Monday's gun rampage at a private Christian school in Nashville, Tennessee, which left three nine-year-old children and three adults dead, local police described the shooter as a young female teenager.

Within hours that description had changed to that of a 28-year-old woman. And shortly after that, the authorities pivoted again, revealing that the shooter, Audrey Hale, had in recent times identified on social media, including a LinkedIn account, as a transgender male.
