That story about Gen "Blackjack" Pershing shooting Muslims with bullets dipped in pigs blood, and the burying them with pigs isn't true; it's just an urban legend.
It's been researched, and there is no evidence that he did anything of the sort.
His men did have to shoot some Muslims. He then wrote to them:
[Pershing] :
"I write you this letter because I am sorry to know that you and your people refuse to do what the government has ordered. You do not give up your arms. Soldiers were sent to Taglibi so that you could come into camp and turn in your guns. When the soldiers went to camp a Taglibi, your Moros fired into camp and tried to kill the soldiers. Then the soldiers had to shoot all Moros who fired upon them.
When the soldiers marched through the country, the Moros again shot at them, so the soldiers had to kill several others. I am sorry the soldiers had to kill any Moros. All Moros are the same to me as my children and no father wants to kill his own children . . ."
Pershing also wrote:
"There was never a moment during this investment of Bud Dajo when the Moros, including women, on top of the mountain, would not have fought to the death had they been given the opportunity. They had gone there to make a last stand on this, their sacred mountain, and they were determined to die fighting . . .
It was only by the greatest effort that their solid determination to fight it out could be broken. The fact is that they were completely surprised at the prompt and decisive action of the troops in cutting off supplies and preventing escape, and they were chagrined and disappointed in that they were not encouraged to die the death of Mohammedan fanatics."

But I like the story anyway.
True or false, it's a great story. I'd like to believe there's something to it! But, you gotta imagine with a quirky smile of Porky Pig doing in bin Laden!
