Let me start by sayiung that this story is hilarious, and for all of you complaining, he thought that one blow to the head would kill it, he didnt want to torture it. We had the same situation with a crow in our yard, it was sitting there dying, so my mom gave our neighbor a shovel to kill it, and he hits it, nothing happens, so he thinks he should try to decapitate it with the spade of the shovel, after one stab the thing starts waddling off.
And the poor turtle. Come on people, those ducks and frogs probly have suffered plenty as well. And for everybody saying to put it in a bag, honestly think about it, its a big ass snapping turtle, Would you get that close to something that can take off your fingers?
