Why do the media always fall into the Hamas trap?

Did you notice, during the recent mass riots on Israel's border with Gaza how the Western media played their knee-jerk role of turning the violence into an emotional defense of Palestinians and an attack on Israel? Why do the media always fall into the terrorist trap? They always talk of Palestinian dead and not Hamas or Islamic Jihad dead. The latter would be more truthful, but it wouldn't make such tear-jerking headlines, would it? If truth be told, telling the truth would put Israel on the moral high ground but that would be against editorial intention. Tales of dead babies win every time against a tale of Jews defending their country against a fomented mob of 40,000.
