A neighbor called the police who came while I was outside trying to figure out who was throwing things. They saw a really, really drunk man in the window of the house and tried to talk the guy out, but he wouldn't budge. They left and told me to call again if I heard any more things being thrown.
About fifteen minutes later I heard another glass bottle, so I called. They tried to get him to come out and eventually got him, gave him a medical evaluation and arrested him.
