Of all the revelations that have rocked the Israeli army over the past week, perhaps none disturbed the public so much as the video footage of soldiers forcing a Palestinian man to play his violin.
The incident was not as shocking as the recording of an Israeli officer pumping the body of a 13-year-old girl full of bullets and then saying he would have shot her even if she had been three years old.
Nor was it as nauseating as the pictures in an Israeli newspaper of ultra-orthodox soldiers mocking Palestinian corpses by impaling a man's head on a pole and sticking a cigarette in his mouth.
But the matter of the violin touched on something deeper about the way Israelis see themselves, and their conflict with the Palestinians.
The violinist, Wissam Tayem, was on his way to a music lesson near Nablus when he said an Israeli officer ordered him to "play something sad" while soldiers made fun of him. After several minutes, he was told he could pass.
It may be that the soldiers wanted Mr Tayem to prove he was indeed a musician walking to a lesson because, as a man under 30, he would not normally have been permitted through the checkpoint.
But after the incident was videotaped by Jewish women peace activists, it prompted revulsion among Israelis not normally perturbed about the treatment of Arabs.
The rightwing Army Radio commentator Uri Orbach found the incident disturbingly reminiscent of Jewish musicians forced to provide background music to mass murder. "What about Majdanek?" he asked, referring to the Nazi extermination camp.
What goes around, comes around.
Think there is any doubt we have some of these things going on in Iraq? A government (here Likudnicks like Sharon) set the tone...here the Bush Administration does, and it is a grievous one.
