IDF Solders Infiltrate Palestinian Stone Throwers

This seems to be a regular tactic employed by the IDF. It all seems rather scandalous to me.

Bil'in residents: Undercover troops provoked stone-throwing

By Haaretz Service and Itim

Prison Service troops disguised as Arabs incited Palestinian youths to throwing stones at Israel Defense Forces troops during a weekly demonstration against the separation fence in the West Bank village of Bil'in, village residents said on Friday.

The residents said that the disguised troops told the youths to throw the stones and then joined them in doing so. When they were asked their identity, they presented themselves as Arabs from Lod, a city in central Israel, who arrived with the Israeli and foreign demonstrators.

When the troops, members of the Prison Service special unit Masada, did not heed a request to show identification and were found to be in the possession of firearms, their identities were reportedly exposed. IDF soldiers came to the scene and dispersed them.

A few months ago, the same unit was accused of similar activities in a Bil'in demonstration, after which a military court judge ruled that the unit lacks the authority to operate in the Palestinian territories.

This puts a lot of weight behind claims that at least some violence by the Palestinian people is politically useful to Israel.
