Doesn't change a thing. It's simply not illegal to enter your own home simply because there's an intruder inside whether you believe you might be in danger or not.
It might not be the smartest move from a safety perspective but it just isn't illegal and there is no statute you can cite that will support that position. You might not be doing yourself any favors if you call the police and say, "I just saw a guy go in my house while I was at the neighbor's house across the street. I'm going over to my house to kill the son-of-a-bitch! You better send the cops." But simply entering your home knowing there might be a threat to you or your property inside is not illegal.
