This doesn’t suggest anything about the effect of rescue squads. Despite the difficulty of recruitment and training, we still know rescue squads save many climber deaths. So why would removing the squads reduce deaths?

This suggests that removing rescue squads would lead to less accurate recordings of death and injury counts. That doesn’t explain why there would be an actual decrease in the number of deaths and injuries of climbers.

This suggests climbers might not expect rescue squads to save them. But if rescue squads do save lives, why would their absence reduce the number of deaths and injuries? We still don’t know.

If there are so many unprepared people, rescue squad would seem to be very helpful. This doesn’t explain why removing rescue squads would lead to fewer deaths and injuries.

This suggests that having rescue squads could attract a higher number of less competent climbers, because the presence of the squads makes climbing seem less risky. Removing squads could make climbing seem more risky, leading to fewer less competent climbers and fewer deaths.
