You merkins crying about 1 punch kills are so f**king stupid. Punches don't kill people the after effects do. Ie falling to the floor and cracking your skull. The players play on a grassy field not concrete. Truth is you can do more brain damage to a person with a stiff palmed slap to the head then with a punch.
The reason why boxers end up with so many head injuries is because of the gloves. The added weight and type of impact is what causes detached brains and concussions. MMA gloves and bare knuckle punches do more external damage ie cuts and abrasions but do very little internal damage due to the type of impact.
The mass hysteria of one punch kills has more to do with a king hit to the back of the head or Neck and people falling onto table corners and concrete after being KO'd and cracking their skulls or getting concussed and not getting treatment and dying in their sleep.
Seriously people like Bunniesmong who bang on about it. Really have 0 clue what they are talking about.
I can't believe that you are actually accusing others of having no idea what they're talking about after posting such nonsense
first of all I suggest you familiarise yourself with what a concussion is, what causes them and their effects

Secondly. yes a slap delivered with enough force certainly can cause a concussion but to say they cause more damage than a punch is erroneous
Thirdly. Yes Sometimes, people take a hard blow to the head and then fall down and hit their head again, worsening their bruising and swelling.
But a Punch itself certainly can cause a lot of damage. depending on the angle a person is hit and how severe the blow is, swelling in the brain may occur. For example, swelling can start in the anterior portion of the brain just above the eye in a frontal head injury. The base of the skull contains irregular bones, so if a person gets hit there, their brain can swell rapidly, where pressure in the skull -- called intracranial pressure - beings to rise suddenly.
If intracranial pressure rises too high there is not enough "cerebral perfusion pressure," which means the blood vessels can't accommodate this added pressure. With less blood flowing to brain tissues, specific regions such as the brain stem do not get enough oxygen and can rapidly swell, and a person can lose consciousness or fall into a coma,
There was an incident in Salt Lake City where a player punched an official during a game. the referee did not hit his head on the ground on the defining blow and sadly died in hospital as a result of his injuries

There was another terrible case in Michigan, where a player again struck a referee. this time the victims head did hit the ground (a grassed field) which contributed to his death
