The Huffington Post gave the news about Israel releasing Palestinian murders the screaming headline treatment, and exhibited some subtle bias along the way:
Note the difference between the two sides, in terms of who is holding the picture of the deceased/imprisoned relative.
The Palestinian woman's face is shown clearly, looking at the camera.
Israeli faces are cut off, as the woman's holding the picture is, or blurred, as the man's face in the foreground is.
For a newspaper without a long history of avoiding showing pictures of Israelis, I wouldn't think it was on purpose. But because it's the Huffington Post, I think it probably is. Why show Israelis if you don't have to?
