Someone went into my back yard and took a trash bag out of my barrel. I wanna catch this fool. But the only thing I can think of is to have a motion sensored light out back i dont have, and cant afford) or keep my dog out back(which I wont). I need something to alert me if someone is in my backyard. any suggestions on how to catch this prick? It could very well be a private investigator that my moms scumbag bf knows. Could be anyone. But I wanna catchy him and detain him and call the cops. (if hes looking for shit) if hes just a bum looking for food than i dont care and I dont wanna get someone like a bum in trouble.
