You have a valid point. The officer lost his cool, but when watches the entire video of the days activities one can see the same Dane being unlawful, harassing the IDF and the Dane would not comply to verbal orders. The officer should have arrested the Dane and not struck him, but I think the Dane got under his skin which yes is undisciplined. The Dane deliberately provoked the officer over and over again, and it was a natural reaction when the officer struck him.
