I once made the mistake of aiming my camera at something while strolling in the Jewish Quarter of Jerusalem on a Saturday afternoon. Then I noticed a group of little girls stop playing and start yelling at me in Hebrew. One of them, noticing I had no idea what was being said, came out with a shake of the finger (index, BTW) and "No pictures on Shabbat!" She had a look on her face that said she meant it and if she'd had a rock, and in spite of her being around twelve years old, she'd have probably put one right between my eyes.
I took no offense, it's their country and customs, but this story rings very true.
they threw stones at soldiers reporting for duty on day of the the’73 yom kippur war until they were told what was happening.
