A different tweet noted that the same brand of tear gas was used in Egypt's Tahrir Square. As reported here last December, those shining shell casings, as well as the rubber-ball variety and spent stun grenades made by the same company, had decorated a tree in Bethlehem's Manger Square at Christmastime as activists gathered those used by the Israeli military less than two kilometers away in Aida Refugee Camp and displayed them for holiday tourists.

A sign hung by activists on a tree in Bethlehem's Manger Square among used tear gas and stun grenades reads, "This is the USAid to the Palestinians." (photo: Ryan Rodrick Beiler/Activestills.org)
