even when you suspect a hostage situation what's the problem with politely knocking and waiting if you get a friendly response? I once pulled over a few blocks from a friend's house, so I could call her and get a few final directions. A man from the house I had parked in front of instantly started talking ominously and yelling at me. I think that guy was a meth head crazed out of his mind. In the back of my mind was the possibility that he'd bring out a shotgun and start blazing away at me. (Yes, my friend didn't live in a great neighborhood.) The police here have to be prepared to deal with people like that. I think friendly looking police androids are going to be quite helpful.
