Guaran fucking tee you the cops a) know all about her already and b) regularly swing past her house to have little chats to her about her behaviour.  Notice, if you will, what happens when a neighbour enters the building... eyes go down, she shuts up. She is what my fucking fat ass sociopath sister will be in ab9ut 20 years if she doesn't have a fucking coronary first. She knows she's well over the line but she knows how to gaslight so no one else can actually witness anything.
