A little more detail: This guy had wandered over from a party next door. It was almost 1 a.m., and during the holidays I work really late, so I came home, put my stuff away, and when I turned around there was a guy standing literally at my window, on my porch, pissing on my house. I walked out and started screaming at him (I know, probably not smart) to get the fuck off of my property. He said, "I'm just takin' a leak," finished his business, zipped up his pants, and leaned against the porch staring at me. That's when my brain caught up with what I was doing and I went back inside and called the cops. My porch runs the length of my (very small) house. The porch is open without a railing, and at this time there were also several other men sitting on my porch right under my bedroom window (closest to my neighbors yard). When I called, Weld County dispatch first told me that the police were "too busy" to come out, and I ended up on the phone with a cop. He asked if the porch was fenced (no) and if it could be seen from the main road (no). I stupidly thought he was trying to locate my house, as it is hard to find. According to the laws in my city, once you ask someone to leave your property and they refuse, it is trespassing. I told them multiple times to leave my property, and one of them had the nerve to tell me "I can sit where ever I want."
