Here's a report about six Israeli trauma experts visiting Boston in the aftermath of the bombing at the Boston Marathon. They're members of the Israel Trauma Coalition for Response and Preparedness (ITC), and were there to help with advice, as they have done evidently in other parts of the world after terrorist atrocities. The report quotes a Boston official as follows:
We had brought in other experts to speak about trauma, but the Israelis came with a level of practical real-life experience that brought it to a new level.
That's a kind of real-life experience Israelis could do with much less of, but it's one of those facts that fails to impinge on the bigotry of the bigoted.
