Reading the transcript of the 911 call, the reaction of police makes even less sense!
“She’s old so she can’t get around too well, but,” the employee said. “Looks like she’s walking around looking for something, like, vegetation to cut down or something. There’s a bag, too.”
When the operator asked if the woman "came at someone with a knife ..." the employee said, “No, she just bringed the knife onto the property in her hand. She didn’t try to attack anybody or anything. We haven't closed in our fence in the back yet and she walked through there."
