I usually stay out of these scenarios, but what the heck..
How are these guys armed? Did you see a handgun tucked in a belt? Or are they walking around your house with shotguns in hand?
If I had a chance of getting these guys, I'd be tempted to do it. I'd want to stay concealed. However if they start shooting and don't see me they might shoot up the stairway, slinging stray bullets toward my family. I mean, where else would an awakened homeowner be shooting from? If they see where the shots come from, of course they will be shooting at me, and that's not good either.
