armed and suspected man in Sheikh Jarah demonstration

Last Friday in the weekly demonstration in Sheikh Jarah (23/4/10) a suspected man was outed by a activists. He was seen spying on demonstrators, collecting information and reporting it. He was also recognized for doing the same in other demonstrations in Sheikh Jarah.
When he noticed the camera and was called out by activists, the man started running to a car that drove him away. In the first photo it seems that the man is carrying a gun and should be considered armed and dangerous. Other activists should be notified when he is seen.
