I stole this video from EDR DEFENSE GROUP LLC. We can see (or guess) several low cost safety implementations that help give you a chance of mounting a proper counter offensive while waiting for the police to arrive.
The screen door was no match for the bad guys (open under 20 seconds), but I added a layer of time delay and specially noise. I believe the main door was metal or very solid wood, with good long bolts and strike plates with long screws deeply driven in the frame. It made what it was supposed to be an instant breaking and entering into a long hard job.
And the camera. What a beautiful thing is to know what is making all that racket on the other side of the door and specially how many. At around 00:25 you can faintly hear somebody inside the house, possibly making a verbal inquiry and the bad guys immediately went with “Police!” or rather the slang-ish “Pooolice” which kind of defeat the purpose since cops do not talk that way.
Unfortunately that is all the video there is plus no story found that would tell us what happened and how long it took. Also, the fact that seven crooks wanted to break into home is the best possible example of why you actually need magazines with as many rounds as you can handle. It goes without saying that if the crooks managed to finally get in, there were baptized in the Church of Armalite or the Church of Avtomat.
Check Youtube for videos on how to reinforce your door. There are simply stuff that is worth pennies like 3 inch nails to not expensive plates for the door and door frame. As for security cameras? take you pick, there is a flood of new and affordable stuff in the market. I have been thinking about adding another camera up front in case the bd guys decide to cover my door bell cam. I want live tracking!
I do have one doubt that I may send over Andrew Branca for examination (If he has not covered it already and I missed it). Doing a Joe Biden and shooting blindly through the door is legally very risky, but how about this case when we have seven individuals at what looks the wee hours of the night pretending to be cops trying to break in and you have them live ans in color on camera?
