PalArab student stressed during finals. So he started shooting.

From Ma'an:

Employees in the Nablus education directorate office were shocked to hear shooting on Tuesday coming from inside the office of the director, Lutfi Yassin. When they rushed to the office, they found an armed member of the public; there were no casualties or injuries.

Yassin, 50, told Ma'an, "An armed man broke into the office and shot inside it when we refused to give him approval to sit the 'Tawjihi' [end of school] exams because he did not meet the conditions for such exams."

Eyewitnesses said that the angry man repeated shooting in front of the department when he was forced to leave by other employees.

Why are people surprised that PalArabs who grow up learning that violence solves all problems start using violence to solve all their problems?

Keep in mind that this is not even in Gaza.
