Wallee The Robot
If he had a tourniquet applied correctly on him, he probably is going to be doing much more screaming and much less talking. Having one applied and having to leave it on is some of the most excruciating pain you will ever have to deal with. Also you don't remove and then reapply it. Once applied you should leave it unless you can control the location of the hemorrhage. You would rather he lose the arm than risk losing his life.
One of the saddest lessons of history is this: If we’ve been bamboozled long enough, we tend to reject any evidence of the bamboozle. We’re no longer interested in finding out the truth. The bamboozle has captured us. It’s simply too painful to acknowledge, even to ourselves, that we’ve been taken. Once you give a charlatan power over you, you almost never get it back.
