Hammer Time

I just remembered something really bad. Back in the 80s I saw a documentary about some African dictatorship. (Sorry, can't remember exactly which one). Anyway, in the prisons under this regime, a popular pastime for the guards invovled two political prisoners and a hammer. Sit them on the floor, give one of them the hammer and tell them to beat the other person to death with it. If he refuses or hesitates, you give the hammer to the other guy. It raises several interesting philosophical issues. What would you do? Who the fuck thought it up? Don't think about it too long though; it's the sort of thing that can mess your head up. http://www.amnesty.org/ do their best to prevent such things from happening again.
