goes along with this.
Upon seeing the above, I decided to do some research on the whole POE thing. There's a lot more to it than I could've ever imagined! This I found to be especially thought-provoking:
The point of entry into a house, be it a door or a window, is referred to as the fatal funnel. The occupants of the house need only aim their weapons at this point of entry and wait for the target to appear. That target is the law enforcement officer, and at that moment, the officer has no cover and more than likely no idea where the armed occupant of the house is located. The officers are generally back-lit, so their eyes must adjust to the lighting, or lack thereof, in the house. The armed occupants are presented with a clear target and need no time to adjust to the lighting. The officers may have little or no idea of the layout or floor plan of the premises and will require time to acclimate to their new surroundings. The armed occupants, however, need not acclimate themselves, for this is their home turf.
Moreover, the armed occupants know what they intend to do, whereas the officers only can infer whether the armed occupants intend to fight, flee, or surrender. This creates a situation where the occupants fire first because the officers cannot fire until they have determined the occupants' intention to resist. Such encounters in very close quarters frequently make the initial exchange of gunfire conclusive. The armed occupants may not consider possible harm to innocent bystanders, but the officers must. -- Special Agent Michael Bulzomi
