The transgender shooter who allegedly killed two of his family members at a high school hockey game Monday was armed with two handguns, both of which were acquired legally.

The transgender suspected shooter, Robert Dorgan, went by the name “Roberta.”

WION reported that the guns possessed by Dorgan at the time of the shooting were “a Glock 10mm and a SIG Sauer P226.” They also noted that Dorgan had a concealed carry permit from Florida.

Breitbart News has repeatedly shown that the majority of high-profile shooters during the past 19 years have acquired their guns via background checks.

Below is a short list of some of the high-profile attackers or alleged attackers who passed checks to acquire firearms:

Despite the fact that so many attackers acquire their guns via background checks, one of the left’s more prominent knee-jerk reactions to high profile shootings is a call for more background checks.
