I'm getting tired of seeing stories like the one portrayed in this New York Times/Reuters article - namely, some Afghan sepoy shooting NATO troops, most often Americans. I have imagined a response that would either make things better, or much worse.
Most often the shooter gets shot himself, as this one was. It might deter future shooters if this turncoat was buried sewed inside a fresh pig hide. Particularly if the desecration was made public and announced as policy going forward.
