Whilst it's sad for the people who knew the deceased and have some sympathy for them, I tend to come down more on Darren and Snoo's side of the fence with this one. It's not the first time this has happened, and sadly I'm sure it won't be the last.
There is no excuse for someone recklessly endangering the safety of innocent riders on a coaster train, particularly when said coaster leaves riders exposed in the way an inverted coaster is. What if the people in the front row had collided with this stupid individual at speed? We've already had the horrifying injuries sustained in the Smiler accident earlier this year. I hate to think how much damage a collision between a human leg and a human body could do at 50mph, but I wouldn't be surprised if it could have caused life changing injuries to one or more of the riders.
I don't see this any differently from someone who is driving a car whilst drunk, or overtakes someone on a blind bend. IMO, entering a restricted ride area like this really should be viewed in much the same light. I guess media coverage has something to do with it, as reporting always seems to focus on the tragedy of the death of the foolish individual, with little or no mention of the fact that they recklessly put far more people at risk with their actions.
