This video - again taken from the extended CCTV video released from "Nakba Day" protests in Beitunia - isn't a smoking gun, but it sure raises some questions about what may have been pre-planned.
It shows the events in the three minutes between the "botched Pallywood" video I showed (which now has over 20,000 views) and the first incident with Nadim Nawara. Clearly, one of the masked leaders of the riots also is good friends with photographers on the scene, and they manage to be at the right place at the right time.
