All of you must be on the same page. If one isn't then it makes it very difficult to get him out. It sounds like just the fact that you and your sisters are breathing is enough to get him to go off. Next time he does, call the po-po and have him arrested. Once he is out of the house and in jail, get a protection order. Once that is in place, get the eviction started just to be safe. The eviction shouldn't be needed, since typically the protection order does not allow the person to be in the same place as the victim, but I've seen a temporary protection order expire and the person come back into the house because they had been living in "temporary housing". The the eviction had to be done, while the person was living there. Talk about a sticky situation.
But when a long train of abuses and usurpations, pursuing invariably the same object, evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new guards for their future security.
Translation for the intellectually challenged: If the government screws the people too much, it is the right and duty of the people to revolt and form a new government.
