Oakland Tech students robbed at gunpoint. In class.

Oh, and AC Transit needs some "No Food, No Drinks, No Guns" signage. How frustrating.

Two men in their early 20s entered a classroom at Oakland Technical High School shortly after 8 a.m. Tuesday and robbed three students at gunpoint, according to police .... The robbers had taken an AC Transit bus to the North Oakland high school that morning, reportedly harassing some of the students on the way.
