I understand that and if you sign on the dotted line then the deal is final, I get it. Ask yourself this though, do you really believe these companies can't be held responsible for injuries and deaths?...I can't bring myself to support that. I just can't. People want to be guinea pigs? fine but they should be compensated for injuries or whatever happens to them and not be shunned or ignored. No company should be immune to this behavior. What about the Hippocratic oath. These people swear to treat people...wtf
