Massad is good, but he is not perfect. One size does not fit all.
I would not hesitate to take his LFI (Lethal Force Institute) course if I could afford the fee.
However, you kinda haveta know your person. I've been reading his stuff for over ten years, starting with his column in Combat Handguns.
Here is what I have come to think.
I think he spins and adds drama just a bit to his legal articles and self-defense stuff. Sometimes a little more, sometimes a little less. But, if you just factor that in, "Oh, that's just Mas being Mas." And, subtract a bit for it, you're probably right on the money.
On rights, I have a big objection with him. He feels nobody should be allowed to carry in public unless trained (read CCW permit) because the untrained defender might hurt or kill an innocent accidentally. He's pretty forceful on this point. But, he also completely misses the point about government and rights. None of this changes the paragraph above, though.
He's obviously pro-cop. The video in the OP proves that fast enough. He has a number of articles and brief descriptions about police shootings--he's been an expert witness for years. I cannot recall a single one where the cop was mentioned to do anything wrong to the citizen, just wrong tactics if anything. It is to the point where I have come to suspect he may be deliberately overlooking the possibility of wrongful cop conduct. Now, this is based entirely on his print writings. I've missed all his internet TV stuff in the last few years, so I don't know if he's criticized bad shoots like the BART subway shooting in CA a couple years ago, or any others.
So, on the balance, I would say that he is a very good self-defense authority (you just have to leaven some of what he says or writes).
