I'm surprised we haven't seen a study about the relative stopping power of rocks and sticks from our government recently.
I'd like to see a study of the lethality of fists.
They are a lot deadlier than Hollywood has portrayed, a lot dealier than people generally think and handgun bullets are a lot less lethal than Hollywood has typically portrayed.
I don't think the current administration would fund any study like that since Holder has even said that the concept of self-defense has been expanded beyond reason and Stand Your Ground laws need to be repealed.
