This is fact. Don't really give a chit what you believe, or don't.

"Goransson et al. were the first contemporary researchers to present compelling evidence for remote cerebral effects of extremity bullet impact.[37] They observed changes in EEG readings from pigs shot in the thigh. A follow-up experiment by Suneson et al. implanted high-speed pressure transducers into the brain of pigs and demonstrated that a significant pressure wave reaches the brain of pigs shot in the thigh.[23][38] These scientists observed apnea, depressed EEG readings, and neural damage in the brain caused by the distant effects of the ballistic pressure wave originating in the thigh."

"The scientific literature contains significant other findings regarding injury mechanisms of ballistic pressure waves. Ming et al. found that ballistic pressure waves can break bones.[47] Tikka et al. reports abdominal pressure changes produced in pigs hit in one thigh.[48] Akimov et al. report on injuries to the nerve trunk from gunshot wounds to the extremities."
