Clint's a good dude, good at what he does and I have a great amount of respect for him. While he does dispense some sound advice in the video, not all situations are going to be carbon copies of each other...he even stated in the video the scenario would be dependent upon different factors..and as some on here have already said, when you have other family members in the house, especially kids, it changes everything.
Personally, I believe we have a moral obligation to ourselves and our loved ones to prepare for unwanted person(s) forcibly crossing the threshold...really no different than preparing for an unwanted fire in the home. Trying to figure all that stuff out when the ball drops may not work out too well. Planning ahead, so that everyone knows, "If X happens, I should do this" is no guarantee of a good outcome, but there is a higher likelihood of it with preparation vs just winging it.
The advice Clint gives is a blade that's got two edges. While locking yourself in a secure location and making "them" come to you may be safer than you getting ambushed, once you call 911, you have placed yourself in "dependency" mode. You are trusting that whoever shows up to handle the problem is professional, proficient and can think on their feet. In some cases, that may be exactly what you get...in others, not so much. Thing is, you ain't gonna have a clue what sorta gum ball's going to come out of the machine once you put the quarter in the slot and turn the handle. Not trying to bash anyone, but just being realistic. I know..."training / trained professional". Well, lemme tell you something about training from my observation(s): I know some folks who have been at a job for quite a while and have endured hundreds of hours of training, but when they roll up with smoke/flames showing, they lose their minds. Being able to think clearly goes out the window, they fall apart and they lose their ability to make good, solid, common sense decisions...you don't even have to see it, but can hear it in their voice over the radio.
Long story short, you may be equipped to handle the situation much better than those you have called due to your preparation...taking stuff seriously, being committed to those you care for, practicing/planning religiously and constantly evaluating plans/practice. Majority of the time, you will get out of it exactly what you put into it. If you half-ass it, you cannot reasonably expect to see stellar results if/when you have to put your preparation into practice. Ultimately, the responsibility for the safety and well being of me/my loved ones falls on my shoulders and it's why I do everything I possibly can to make myself/those around me better.
