When he had all he could tolerate and after trying other methods, he rounded up some of the terrorists and made them dig their own graves. He then had them tied to posts and made them all watch while some pigs were slaughtered before them.
Bullets were dipped in the bloody pig fat and loaded into the US soldiers rifles. All but one of the terrorists were executed. The bodies were unceremoniously thrown in the pits, face down so they could not "see" Mecca. Pig entrails, fat and blood was then dumped on top of them.
The last remaining terrorized terrorist was set free to tell his living associates what he witnessed. There was no terrorism in the Philippines for over fifty years. This story or variations of it have been in circulation for years and I don't know if it's true or not. Sounds like it's worth trying to me.
