That's quite all right --- all are free to voice their opinion.
But if you want me to accept anything as fact, you must present evidence that refutes the conclusions these experts have reached.

Brain contusions commonly are identified in patients with traumatic brain injury (TBI) and represent regions of primary neuronal and vascular injury. These edematous lesions contain punctate parenchymal hemorrhages, which are termed microhemorrhages. By definition these parenchymal bruises are found on the surfaces of the brain. Blood may extend bidirectionally into the white matter and the subdural and subarachnoid spaces.
Contusions are formed in 2 ways: direct trauma and acceleration/deceleration injury. Direct trauma causes injury at the site of impact, which is termed a coup contusion, while deceleration causes injury at a site opposite to the site of impact, which is termed a contrecoup contusion.
In the first mechanism, direct trauma, the head is not in motion. This mechanism may result in a scalp or skull injury.
The second mechanism is related to acceleration (eg, boxing injury) or deceleration (eg, motor vehicle accident), which causes the brain to strike the skull. In an event in which the head is in motion, cortical injury occurs adjacent to the floor of the anterior or posterior cranial fossa, the sphenoid wing, the petrous ridge, the convexity of the skull, and the falx or tentorium. The inferior...
