My friend’s husband, who was elderly, was sitting outside in a lawn chair, a little distance from his back door. Rather than yell for his wife to help him in the house, he leaned toward the door - misjudging it’s distance, and fell against it - and broke his neck. I think Freddy Gray may have broken his own neck by jerking and throwing himself around. I’ll wait for the facts to be made known, but, just wanted to share this.
But let's look at the possibilities:
1. He broke his own neck, police are exonerated - Blacks riot, because it is "clearly false", he couldn't do that to himself
2. The police broke his neck, and failed to render aid, but are overcharged and found not guilty - Blacks riot
3. The police broke his neck and failed to render aid, police are found guilty - Blacks claim a further foundation for future riots, because police are racist
4. He broke his own neck, but police are convicted anyway - Miscarriage of justice, and Blacks claim further foundation for future riots because police are racist
No matter the outcome, the foundation is laid for more riots in the future... some sooner than others. The forces of evil win no matter what.
Mike Utley, an offensive lineman with the Detroit Lions, fell face first trying to block another player in an NFL game in 1991. He couldn't break his fall. His neck snapped back and was paralyzed.
So, it is definitely possible to simply fall and break one's neck.
