I'm sure they didn't know. Why would the British press want to knowingly print lies? I mean they were all for the War On Terror to begin with. The British press is known for their honesty and integrity, just like the press here in the states.
Okay, enough of that. The Daily Mirror absolutely will not take personal responsibility for this. They knew these were fakes, and yet they didn't care. For all we know the bastards that killed Nick Berg may have been getting their "news" from Britain and not America. And if that's true, and they're seeing this, then maybe that's what convinced them to kill him. Who knows.
