So you know the weight on the form was obtained from a weight-scale? That they weren't just taking his word for it?
So Lee weighed 131 pounds......or a whopping 44 pounds less than the 175 pound man who Brennan saw standing behind a TSBD window while aiming a hunting rifle out of the window.
Not only was the man much heavier than the skinny Lee Oswald..... The man was dressed in light colored khaki clothing...... and Lee didn't even own any light colored khaki clothing.
