room #1 emergency physician, Doctor Malcolm Perry, after he attended to the frontal throat wound, as being an "entrance wound". Doctor Perry stated the neck frontal wound "appeared to be" an entrance wound three times during his press conference. However, medical researchers have found that ER doctors frequently make mistakes with regard to entrance and exit wounds, and both Perry and Dr. Carrico, the other attending ER doctor, later testified at the Warren hearing that with a full jacketed bullet the wound in the front of the throat could have been either an entrance or exit wound; the Parkland ER doctors also never examined the wound in the back and could make no comparisons with it. Within nineteen hours of his press conference statement (but after the autopsy had already been completed), Doctor Perry also described via telephone to Doctor Humes, one of the three U.S. Navy Bethesda Hospital military autopsists, that the neck front wound was originally only "3 to 5 millimeters" in circular width before doctor Perry attended to the front throat wound (Humes documented Perry's "3 to 5 millimeters" wound size by writing it down during the phone conversation), passed through both sides of his shirt collar-front in alignment with the collar button buttoned, about below the center top collar button and collar button hole, in line with the throat wound, and with the threads in both bullet-slits forced outward, showing this to be an exit wound, nicked President Kennedy's tie-knot on its upper left side. Upon clearing the tie-knot the bullet had slowed to about and had started to tumble, traveled the between President Kennedy and Governor Connally, impacted and entered Connally's back just below and behind his right armpit creating an 8 millimeter by 15 millimeter elliptical wound, indicating that the bullet was fired from an acute angle to the entrance wound point, or that the bullet was tumbling, having hit something on its earlier way (presumably Kennedy); according to Connally, the impact of the bullet was very forceful. In terms of the physics of this impact, this means that the bullet imparted part of its momentum to Connally's body and therefore the bullet's momentum changed (in speed or direction or both) upon entering his body; completely destroyed of Connally's fifth right rib bone as it smashed through his chest interior at a documented 10-degree anatomically downward angle, (post-operative x-rays document that some of the
