Sounds like a tough situation. We all have an idea of what we would do in such a situation, but things rarely work out as planned. Ideally if you shoot a home intruder, you set the gun down and have hands visible until law enforcement arrives. That's fine if you KNOW there is no one else, and there is time between securing your house and officers arriving. Sounds like officers arrived to the sound of gun shots, so they probably aren't just chilling outside for a few while you get all your ducks in a row. They don't know what the guy who lives there looks like since none of us where homeowner uniforms. So what do you do of you've barely finished engaging the bad guy and the next person you see is the police coming in? Tough situation for sure.
