By the time APD knocked on my door, at 10:45pm, the school had already been informed. I went to the door with a pistol in my hand and once I saw the uniform, I asked to see an ID through the closed and still locked door. Then I saw there were two of them, both in uniforms and a two patrol cars blocking my driveway. I opened the door and stepped outside. The officers were great BTW and basically said they had no choice, and it might be nothing, and then told me what was reported...I called my son down and the officers talked to him, in my presence. The asshat friend of my son who, from another state called it in was a belligerent Karen if ever there was one. One of my son's had said something to the other and had told his friend about it. It was really nothing at all. I had to call the school the next morning before my boys could return. It was like a really bad case of "telephone". I have no doubt there are good uses of this system, but so far, at my boys school, not a single one had been legit. Since I work security at the school, I get notified of all of the reports that come in to the school.
