Sounds like they didn't know what they were doing. In the first place they should have had water. Period. Anyone with any experience at all knows that. Second, they should have treated the guy for heat exhaustion/dehydration, but I don't think any of them knew what they were looking at, so they pushed the panic button. I've seen (and had) heat exhaustion before. I have half an idea of what the symptoms look like and what to do. It would appear that they did not. Even the rescuer, "airmorse", incorrectly wrote that immersion in the lake would harm the individual. If the victim were overheating, it would not be harmful. Indeed, it could be a life saver.
