If they were in the garage, they were already broken in to the property.
It’s like a football end zone, Once they passed over the invisible, but legal, “plane” of the property line without permission they were trespassing and committing a felony. anything past that line is at that point irrelevant, it is ALL PRIVATE PROPERTY.
They have led us to believe that even parts of our private property are public access property and it is totally unconstitutional and we are fools if we allow it.
Need to look carefully at the laws for this state. Shooting in self defense is always justified. Shooting to protect property not always so.
