As we’re rightly reminded frequently in the face of such incidents, we would err if we overgeneralized from incidents like this one:

A homeless woman “was wiping blood off of her hands with a paper towel” after she allegedly killed a homeless shelter coordinator with an ax, police said.

Zaaina Asra Zakirrah Mahvish-Jammeh, a 38-year-old resident of Morningside House shelter in Brattleboro, Vermont, wanted to talk to Leah Rosin-Pritchard, a 36-year-old social worker, in the living room, according to a probable cause affidavit. …

After attacking Rosin-Pritchard, Mahvish-Jammeh then turned to another employee and said, “I like you. It’s Leah I (sounds like didn’t like or don’t like). I like you,” the affidavit alleges.

On the other hand, we would err if we didn’t realize that historical narratives can become established because they may have truth.  Sometimes people are in circumstances like homelessness because they have mental problems.  Axes and knives will do in lieu of guns for the purpose of killing.
