Now I dig that these were two, healthy young men and they had machetes, but having thought in the past about solving such a problem, there's a simple solution, whether you're male or female. It's this:
Why didn't anyone start throwing rocks? If you outnumber the enemy 40-2 or something like that, why didn't they start screaming for reinforcements from the local buildings and heaving whatever came to hand at these swine? Like Glenn Reynolds likes to say, "A pack, not a herd." Well, this was a herd and a particularly docile one at that.
Crazy. Just crazy.
