It's laughable because tall people can manipulate their height in many ways by kneeling, squatting, laying down, siting on something, leaning on something, bending over, etc. Based on Maggie's wounds not appearing to come from a shooter that actually knew what he was doing, I'm going to guess that whoever was shooting was not holding the gun up and aiming as one normally would in the position one normally would when firing a rifle. So to have this analysis saying it was a person exactly this tall is ridiculous.. the angles that Paul was shot from shows that the person wasn't standing up firing straight on. So now he is analyzing Maggie's wounds as if the shooter was standing up.
