I'm not saying that it was in any way a touniquet...only that it might have been the lightbulb that made Karr think of it. It goes to his background...Say Red Cross certified rather than a military background.
So you were suggesting it was done by someone with a Red Cross or First Aid type background, but it was not USED as a tourniquet and you were not remotely trying to say it was...thanks for the clarification. I was initally perplexed by your post.
