Jim Marrs actually had a course at University of Texas Arlington on the Kennedy Assassination—an amazing guy.
Any of his many books are worth the read.
For those who don’t know him. Jim’s analysis of the JFK assassination was based on painstaking on the ground interviews of witnesses (what actual reporters used to do—today a forgotten art form).
His UFO and other conspiracy books are great introductions to the subject for those with open minds.
Did he report that the majority of witnesses said the shoots came from the direction of the School Book Depository building? Did he interview Oswald’s coworkers who heard sounds of the bolt action and shell casings hitting the floor above them? Did he talk to the guy who saw the gun protruding from the sixth floor window?
I doubt it.
