Earlier tonight, I was in my living room playing videogames and I hear a little girl crying. She walked past my window, without anyone with her, and looked in my window. She didn't go away and, being alone and crying, I open my back door, not the screen door, and ask if she's okay, and if she's alone. She says she is alone bacause "he left" and that "he was being mean". I asked who was being mean and she said her daddy. She asked to come in and I said no, instead I went outside and crouched down to her level. After she said "he was being mean" a few more times, I asked how, and she didn't say anything. Just to be cautious, I asked if he hit her, and she said "he was being mean" again. A man came up the stairs and walked toward us. Since he looked like her, and he didn't seem too phased by a woman and a little girl talking on the patio after dark, I assumed he was her father, and I cocked my head at him and asked her "do you know him" and she nodded. He walked right up to us, ruffled her hair and said to her "what are you doing, I thought I told you to stay inside". I was still crouching, and did not stand up or say anything as she followed him and they went back to their apartment. Before he went inside, I said "hey" to get his attention and he looked at me. I asked him "you don't hurt that kid, do you, because that's fucked up man" because of how many times she said "he was being mean" and, honestly, because I was also abused, and I felt like I had to say something. He said "I don't hit my kids" and I asked "really?", at which point he asked if I wanted to check her to make sure. I replied "I know it doesn't always leave bruises". He said again "I don't hit my kids or anything" and he told his daughter to tell me, but she was already inside and wouldn't come back out. We stood there for a a few seconds, and he said something which I honestly can't remember, but it wasn't anything threatening, it was like a "bye" or something, and he went insde and shut the door, and I also went back insde my apartment. None of this conversation was spoken in raised voices, and no threats were made by either him or myself. At no point did I ever touch the girl, and at no point did she enter my apartment. Although, I was kind of shaken up by the whole thing, and went back to playing videogames for about half an hours until I finished and went back to my room and got on the internet, trying to forget about it and calm down. About fifteen minutes ago (time now, 11:38 pm), some loud bangs came from my back window in the kitchen, and, being as I was already on edge and kind of feared some kind of confrontation from this guy, and the fact that someone was banging on my window, I took my boken. I found some guy staring in through my window, but when he didn't do anything else threatening and I saw he was uniformed, I held my boken in a non-threatening manner, one handed at my side, and opened the door. He told me to put my "stick" aside and told me to come out to speak with him. Being raised to always confirm that it's actually the police and not an abducter, I asked him to show his badge and talk to me through the screen door. He told me again to put my boken away and I apologized, and set it down, leaning it against the table, out of reach. He told me again to come outside, but I told him I didn't know if he was a real cop, and that if he wanted to speak to me, he could do it through the door. He said he couldn't speak to me without verifying my identity and asked me for my I.D., and said I could call 911 to ask if he was real. I got my wallet, but when I reached in to get my I.D., he said something that again, I honestly can't remember, but it made me doubt he was a real cop again, because it was one of those things my mom told me real cops would never say. He told me again to call 911 and ask if he was real, I did, and after being transferred to the Tucson Police, and when I gave them the I.D. phrase he told me, they said he was real, and which point I apologized and opened the door and gave him my I.D. After radioing in my info, he asked why I wrote in chalk on the guy's wall. I said I hadn't left my apartment and that I had no idea what he was talking about. He accused me a couple more times of doing it, saying "I think you did" and asking to see my hands, and asked why they had chalk residue on them, despite being perfectly clean. When I asserted again that I had not left my apartment, and in fact, have not left my apartment all week, he asked what happened with the girl. I told him she was out alone, crying, and I asked if she was okay, and that she said her father was being mean. I told him that the father "came from over there", at which point I pointed to the stairs he came up, and that we had a calm conversation and went back inside out respective apartments. The cop said that, based on my explaination, that I was in the wrong and should have left the girl alone, even when I asked him "a little girl? Alone at night, cyring?", he again siad I should have left her alone. The officer then asked again when I had left my apartment and written the threat on this guy's wall. I said again I had not, and the officer said the man claimed to have looked out his window and seen my looking down at the writing. The officer also looked at my I.D. and said that I "drew my e's the same" as the letter from the threat. I aksed to see it, and he said yes. I left my apartment and shut the door, walked over to the other guy's apartment, and looked on the wall for the threat, as that's where the officer said it was. When Ididn't see it, he pointed to the ground, and in handwriting that was obviosuly not mine, the words "dare you, I kill you" were written. I told the officer that it was not my writing, that I write my "a's" and "e's" differently, and that I don't dot my exclaimation marks with x's. The officer asserted again that I write my "e's" the same as on my I.D. and when I reached for it to see myself, he pulled his hand away and did not let me see my I.D. We then went back to the doorway of my apartment, and I said again that I had not left my apartment, the handwriting wasn't mine, and even offered to write the same sentence for him, which he declined, and that there were no threats or anger in the conversation me and the father had had. The cop, again, accused me of writing the threat, and told me that I was being cited. When I asked if I was going to be arrested, he said not at this time, although that the father could, if he wanted. press charges against me, and get a restraining order against me if I "did something again". I asked the cop if, in the future, I was arrested on other accusations, if there was some way if I could protect myself from being falsely accused, providing some other evidence than "I've been in my apartment all night". He declined to answer saying things along the lines of "that's the future, it's not now, I can't tell you what to say". I aksed him if this would have any impact on future employment opportunities I might have, and he again declined to answer. He did, however, tell me that my apartment was "crime-free housing" and that I could be kicked out. He told me, in a tone that was somewhat demeaning, that my "all of my anxieties and past" did not mean I could "accuse people like that". He told me to not take any further action and stay away from the father lest he take out a restraining order on me, or other legal action, and left.
