I'd say get a lawyer, because they need to be invited in or they need to feel that lives are in danger at some point. Like somebody had a heart attack and nobody is opening the door. They can freely enter. Like a few months ago I had a friends soon to be ex wife crashing on my couch. She called a crisis line and said she wanted to die or what not and so they called the cops and once the door was open they were inside.
I didn't invite them in, but then again i wanted them to haul her off!
And I was very polite with them mentioned that I all my "deadly" weapons were in the living room (basically nice swords) and they joked around. Now I hate most cops, and hate their attitudes but put up with these two for the fact they were taking a problem off my hand.
But totally get a attorney and see about getting EVERYTHING dropped.
