[Ed. – Not a good guy with a gun.]
Charlie Landeros was a far-left activist who used they/them/theirs pronouns. He had recently lost custody of his child, which is reportedly why he was at the school in the first place. He had a loaded pistol in his person, and extra 9mm ammunition in his backpack. His left-wing activist participation was highlighted by the JustininTrouble blog.
“Landeros was a member of Community Armed Self Defense (CLDC), a group that was created as a “new liberatory and inclusive space for all oppressed peoples to learn about armed self-defense,” according to the group’s Facebook page, which is no longer publicly available on Facebook as of 4 p.m. Saturday,” said a local news report.
The group outwardly hated police. Its Facebook page is archived here.
