Before anyone sees this as a victory, the kid was left legally blind in one eye, the family incurred $90k in medical expenses and it took years to win the judgement. From a story on WKRN-TV in Nashville, Tennessee (U.S.):
As a seventh grader at White House Heritage School in 2006, Jacob Gentry was hit in his left eye with a textbook when his teacher left the classroom, causing him to become legally blind in that eye.
It seemed like a minor injury at the time, but it required four surgeries.
Jacob’s attorney, Jonathan Street, told Nashville’s News 2, “There’s a lot of pain that you go through, his medical bills were over $90,000.”
