That's silly, every little boy has experimented with flight since the Wright brothers. God knows I have, but I did it from an altitude of 10 feet with a couple of lawn umbrellas. Blame the kid for not knowing better, or the parents for not watching him, or physics for letting him die, but Jesus, it's just a natural curiosity, and WWE shouldn't be given that much credit.
Hell, I have personally been injured because of the WWF back in the day. In 4th grade, my friends and I were really into the WWF. One day, we were wrestling, and a 5th grader tried to Tombstone me, and he fucked it up horribly. He ended up ripping a good deal of muscular tissue in my left shoulder, and I was hospitalized for it, and was in a sling for a while. Did I blame wrestling? No. Did my parents blame wrestling? No. The fact of the matter is that boys will fucking be boys, and kids WILL hurt each other. It has been a fact of life since the beginning of time, and just because people have new scapegoats doesn't mean that people should sue.
In my opinion, being sent to the hospital a couple of times as a boy is a part of the life experience of the young male (and the young female, to a slightly lesser extent). I've had torn shoulder tissue, fat lips, broken teeth, broken wrists, burst blood vessels in my eye (from getting the edge of a lacrosse stick head in the flesh of my eyeball, an excruciating experience, let me tell you), fractured noses, etc., and I turned out fine. Getting hurt is a part of growing up, and statistically speaking, some kids are bound to be involved in fatal accidents. While I have sympathy for the family, I do not agree with their blaming a TV program for their child's death.
