Haven't read the Dr. Anderson's book, but according to the author, he doesn't investigate tactics, just the physiology of the wounds.
I have read, many times, the original FBI report, the coronors reports and several professional papers (not gun magazine articles).
I started in law enforcement in 1988 when all of the official reports were first being released so it was a topic of pretty intense study at academy at the time as well as all the LEO professional publications, so yes, I am as familiar with the incident as second-hand information will allow.
My contention is that Hanlon & Dove were unarmed, and untrained in how to continue combat after being disarmed. That makes their failure to react more understandable. Grogan is the puzzler, be cause he had the means to defend himself, and I contend, the opportunity (he had time to exclaim "oh, my god" before he was shot) but for some reason, was unable to. That is a "why" worth looking into further.
