Dear Hisam, father of Ahmed, may he rest in peace: I learned of the death of your son, Ahmed Musa, through a one-sentence newsflash on the Palestinian news station Ma'an last Tuesday: "Ahmed Musa, a young boy, was killed by a bullet of the occupying forces in Nil'in." I was immediately overcome with shock and grief and bitter tears. And above all, that relentless feeling of powerlessness that I know too well.
