How stories are misconstrued in the media

I didn't see the news last night, but heard it this morning. Seems the members of the British Royal Navy were in Iraqi waters when Iranians crossed over and took them. Another amazing story in the mainstream media where they don't have their facts correct in the beginning and want to spin the story to make it look as though it was the Brits fault. Why are they so intent on making the Iranians look good? Well, that's another whole issue I could write a novel about, but I'll leave this as is.
