How have I contradicted myself. It would be relatively easy to bust out the glass and inner frames with a 8" flash light which is what at least one of the intruders were carrying. I am assuming this because they are glass but I have never actually tried to bust out the glass of my own windows. But then again they stood up to gunfire admirably.You contradict yourself here. If someone was making a concerted effort to get in would the doors be easily breached, or not? You say it would be easy using a tool like a flashlight? I have seen dozens of doors breached and can only remember two that took great effort. One was barricaded with 2X4's and the other was a steel frame security door that opened out.
These are steel framed doors with a vertical lock extending into the header at the top and into the concrete floor at the bottom on one door and secured with a deadbolt on the other which extends into the door with the vertical locks.
You are not going to kick them in without effort
And that sounds like a better tactic than the home owner shooting at a perceived threat that he actually COULD seeHis buddy was lying on the floor after being shot and was still in the kill zone. He did what he thought was right to provide some cover for his partner. All he knew was that he was hit. I can't say what I would do under the same circumstances
