“If someone is coming in through a busted out window, I’m opening fire.”
On public property?
I think what you probably mean is if someone was coming through a broken window into your home, and that person was not a fireman trying to put out a fire in your home, and you were not a felon yourself in possession of an illegal firearm, and you were in fear of your life . . .
But of course none of these thing apply to the killing in the Capitol that we are discussing.
“On public property?”
Many justifiable shootings take place on public property.
The use of justifiable deadly force isn’t restricted to property you own.
