I suspect this will end up being one of the cases where the "Reasonable Person" standard comes in. How aggressive were they being in their prank, and would a "reasonable Person" be in fear they were coming in?
Good news (or not) is that there aught to be video of what they did exactly.
I can't read the article behind Fox's paywall, but from my Monday morning quarterback spot, I kinda think the line is did they breech the house. Not even did they walk inside, but did a window break or did the door get kicked open? If not, you have some rowdy unkowns outside. Get a gun, call the police, use the time to prepare your position. If the door opens, or a window breaks, repel borders (PID and "Know your target AND WHAT'S BEYOND" apply, of course). That's just my real quick hot take.
