Why would someone offer a false story like Bush pardoning Bin Laden?

Why would someone come up with a story such as this one:

I have scoured every respectable news sight and searched every list of pardons that I could find and NOT ONE of them reported on this.

If Bush pardoned bin Laden, I would truly think that not only would congress have him for lunch, but if there was anything left over the rest of the general American public would want a piece of him.

This was not the only false news story I have seen the past 2 days, yesterday while doing my turking a news headline came across my computer saying that George Bush had died in his sleep, and gave quotes from white house staff and quotes that Laura Bush had supposedly made, this was utterly revolting to me, and I would be just as disgusted if someone were doing this to a president who was democrat.

I guess in my rambling, I can't help but wonder why people do this, and I gave the sight, The Huffington post a piece of my conservative mind as well.

I don't care if a news sight is Liberal or not,  there is no place for yellow journalism like this in America.
