That governments cannot be allowed to kill journalists with impunity, correct? Everyone from the secretary general of the United Nations to hawkish Republican senators have lined up to make this point and to express their concern and anger.

But is this a lesson that only applies to Middle Eastern dictatorships? Or to Western democracies, too? The United States, perhaps? The reason I ask is that we all now know the name of Arab journalist Jamal Khashoggi, but very few of us know the name of Arab journalist Tareq Ayoub.

The difference between them? An unelected crown prince in the Gulf is blamed for killing Khashoggi, while an elected president of the United States has been blamed for killing Ayoub.

We rightly demand justice in the case of Khashoggi, so why not in the case of Ayoub?

On the morning of April 8, 2003, less than three weeks after U.S. President George W. Bush ordered the illegal invasion of Iraq, Al Jazeera reporter Tareq Ayoub was on the rooftop of his network's Baghdad bureau. The 35-year-old Palestinian from Jordan and his Iraqi cameraperson, Zoheir Nadhim, were reporting live on a pitched battle between U.S. and Iraqi forces for control of the capital. It was just three days after Ayoub had arrived in the country.
