I don't disagree with the rest of your post Chris, but I personally think you're off the mark with this comment. Most people who attack with bats actually end up aiming at the body and legs rather than the head in my experience. Most bat attacks are viscious and savage but typically leave the victim with multiple broken bones, contusions etc rather than dead. Contrary to what the films would have us believe it actually takes alot to kill someone with blunt force trauma as the body is designed to protect against exactly that kind of impact. Knives on the other hand often result in fatal injury and in many cases it is unintentional. The body is not designed to repel stab wounds and even an initially non fatal blow can be become fatal due to blood loss. Knives are also a hell of a lot harder to see coming and move very quickly and can hurt you at even the shortest of ranges without any build up or chambering making them difficult to defend against.
I know its off thread so maybe its worth a thread of its own.
I'll jump into the other thread, but first a bit of clarification.
If someone is determined to kill you, a knife is the easier way for them to achieve it. But that's not what makes a knife more potentially lethal when introduced into a confrontation, mainly as there are a large number of attacks with a knife which are little more than superficial (commonly slashing attacks). Baseball bat/impact weapon attacks, on the other hand, from every conversation I've had with emergency workers, police, reading all statistics I've found etc, have a dominant tactic of attacking the head. In that case, if we were to take 10 attacks with a knife, and 10 with a baseball bat (leaving out simple intimidation, although that reduces the numbers for knife even more [not that a baseball bat isn't used for intimidation, just that a knife is far more common that way]), even if we allow a 50/50 split for stabbing versus slashing (which I think is generous to the stabbing attacks), baseball bats would have 7 or 8 out of the ten being strikes to the head. In other words, the attack with a baseball bat itself is more likely to be a potentially lethal attack, as opposed to a knife, which could be a potentially lethal attack, or not. The reasons for this include a knife being used in an offensively "defensive" fashion (which is what slashing is really about, maintaining distance by creating a "barrier" with the moving knife) in quite a number of cases, particularly when the knifeman is unskilled or has a lack of experience/confidence. And, while they can be quite nasty, and potentially deadly (depending on targeting), slashes just don't tend to result in as many deaths (relatively speaking) compared to stabs, or blunt trauma to the skull.
In terms of your experience with people who have been attacked with bats, all I can say is that goes against all other accounts I've come across. A simple google for "Baseball bat injuries statistics" brings up consistent references to "facial injuries, brain trauma, cranial injuries" etc, with this (old) comment being representative of the most common accounts I've come across:
http://www.ncbi.nlm.nih.gov/pubmed/8483176 Note in particular this section:
Multisystem trauma was documented, with craniocerebral injury being the most frequent, and the most frequent cause of death.
.
In other words, the most common target was the head, and that was the most common cause of death when a baseball bat was involved. It may be important to note that in many cases, the person involved didn't just die on the spot, but may be knocked out, end in a coma, or pass away from injuries over a short time.
