If nothing else, just a move where someone's head/face makes contact with the ground can be scary for reasons other than concussions. When I was younger, I let a friend perform HHH's Pedigree on me (on some cushions, of course). Like any idiots who perform wrestling moves untrained, of course I eventually got a couple of my teeth busted out. This was after we thought we had "perfected" the move, and had done it a few dozen times. One tiny slip-up is all it took, and boom - it took a year for my teeth to get fully capped, and I walked around with weird looking teeth for far longer than anyone should have to...but I still blamed myself, not the WWE.
So there are the deaths, and the concussions to think about; then there's all the other things that could happen. Someone could lose an eye, if the kids don't check the ground properly for sticks, or broken glass, or something similar. A kid performing the move loses his balance for a split-second, and that could result in a broken nose, broken jaw, broken eye socket, the list goes on. Again though, is the WWE really responsible for something like that happening? Maybe it's more a product of the time we live in. Some kids in Colorado shoot up a school, it's Marilyn Manson's fault - or the violent video games they were "addicted to" (no wonder they were the first state to legalize recreational Marijuana, huh? lol).
Some people are just stupid, and others are downright evil. How a kid is hurt or dies shouldn't really matter, it's the kid who did it to him who should be at fault. Also, someone would need to check to see if the kid's parents are competent. I'd be willing to say that 9 times out of 10, it's a latchkey kid who didn't get enough attention from his/her parents that end up being that way. Not that all latchkey kids are "bad", just that the bad ones tend to be ignored more by their parents (or friends, or teachers, or the opposite sex, or whomever). Sometimes these lawsuits are solely about money as well. How much bread can the bereaved parents squeeze out of this company, or that company? It's enough to make you want to puke sometimes.
Obviously there is no such thing as a "safe" wrestling move, even for guys who are trained...but you can't blame the WWE for at least thinking about a move that kids could/would emulate, especially one performed by the "face of the company". Maybe it has more to do with that, than anything. Once Seth drops the title, I could see the move coming back...in other words, I wouldn't bet on seeing Seth do it before he drops the title. That way Seth could get more "vicious", because losing the title made him "crazy". It would be similar to Orton and the Punt, I suppose (and many other wrestlers from the past as well)...but not a bad idea none-the-less. Plus, Seth is a "bad guy". Parents need to explain that only a dirt-bag like Seth would pound someone's head in the ground with their foot. Again, not enough emphasis is being put on the parents, in my opinion.
