This is mostly left out of the story....but it is a guy who attempted to be a woman.
The "article" refers to it as a "woman", See BS actually inserted this line for misdirection and blame shifting, in the story: "According to a recent FBI study, men carried out 94 percent of mass shootings between 2000 and 2013"
I had wondered about this. Women never do workplace shootings. They get revenge in more subtle ways.
