More people should do what I did. When I was building my house, I salvaged a solid steel security door from a office building that was being renovated. I planted steel supports in three feet of concrete for the door frame which I then attached the door to. For extra protection, once the door is shut, I have a steel slide bar at the the top and bottom that I can place into brackets welded directly to the steel supports. The end result being, a cop can kick the door all day long and all he’ll get is a broken toe, ditto with the hand held rams. In fact I’m guessing nothing short of ram attached to a bulldozer is going to budge it and I’m imagine in the time it takes to find one of those. I can contact my lawyer, the press etc. and rectify any “misunderstandings” such as attempts to serve a search warrant at the wrong address.
It sounds like a good installation. It makes sense to make your residence more physically secure.
I like the idea of a second barrier some feet away from the door. The door bell should be at this barrier, so that you can look from the doorway and see who wants to enter your domicile. I saw this in use by a good friend of mine, George "Tex" Ferguson, the highly decorated WWII veteran and intelligence operative. His was installed on the porch of his house. A wall around the rest of the property discouraged entry by other means than the front of the house. The porch extended across the whole front of the house, and was enclosed with a fairly strong welded wire or hardware cloth. A security door and a doorbell completed the installation. You could look through the security door and the hardware cloth to see who and how many people where there.
Tex had made a lot of enemies over the years, I am sure. The "stand off" distance that the second barrier gives you makes quite a difference in your ability to respond to a threat.
A modern version would have an intercom and a security camera to watch the doorbell position. They are cheap enough that we should all install them. Video recordings are doing more to restore our rights than quite a number of lawsuits.
