I think that's a perfectly reasonable expectation, yes? If they reopen this ride and another person dies of blunt force trauma in 6 months, that is a scandal and a huuuuuge problem on many levels. (If they reopen it and someone happens to have a heart attack while riding, that's different of course.)
I gotta say I'm not understanding what is going on here, although if the ride is in fact totally safe I'm glad that it's reopening. It makes me wonder if the initial findings that Kevin died by blunt force trauma were incorrect. As I've said before, it's very hard to think of what could be so different about his particular anatomy that blunt force trauma could have killed him but not be a serious, even if statistically unlikely, danger to other riders.
