Where do you get the idea you don't have that right?
It'll come to you when the guy coming out of the window--who may be the owner of the house--perceives YOU as the threat and shoots your ass.
It was his next door neighbor crawling out of a window. Now I am not the most social butterfly in the world but I do know my neighbors and I can recognize then on the way out of one of their windows at least two out of three times.
Now I am not the best friend of all my neighbors, a couple of them are just not nice people but I am willing to bet a cup of coffee at my house they would all be liking me if I stopped a bad gut crawling out their window.
What the hell was this guy to do? He got robbed, he went looking and saw a stranger crawling out the neighbors window. He may or may not have used wisdom when he fired a warning shot but the bad guy was arrested. That sounds like a lived happily ever after to me.
