I have the kukri knife I bought and my family used to chop the head off a goat.

They eat a lot of goat in that part of the world.
Odds are they were going to be killed anyway.
Seems to me we need to take a gander at Tyson Farms or the Chicago Stock Yards before we judge.
I learned about that in a kukri book.
