Not long ago I came upon a wreck on a narrowing, steep, high traffic part of a trail. Two ski patrollers in attendance had their hands full with the victim so I stopped above the wreck along with a resort employee to try and divert/warn/slow down traffic. A fair amount of the traffic after warning were more focused on getting through at speed than slowing down and they were adding a whole lot of risk of further injury. At the very least they were callous and reckless and I'd have for sure pulled some passes. I can't imagine a reasonable excuse as to those who refused to slow down as all who passed were exposed to the warning.
Me neither and those are not the one I want to defend. I was just saying that some people may fall into the category where they happen to lose control due to some unforeseeable events near a wreck site. And they should not be identified to be the same as the reckless ones, despite the end results are the same. Many before have good intentions, but I don't think that it is right to complete dismiss the slim chance of things that can happen. If it is possible, even 0.1% chance of happening, we should consider that.
