Now, I did not have a chance to ask her what she meant - but here is my understanding. She had been sent there due to someone reporting me as a suspicious individual standing near said location. I can see this because of the hoodie I was wearing. So I am assuming she was referring to me when she responded "it's already coming off" in her walkie-talkie, meaning the nuisance who had roused the attention of campus police (me) was thankfully walking away.
