I personally know an inner-city high-school teacher who has some horrific stories and heart-wrenching stats.
One-third, yes 1/3, of all of her students have had a father or brother murdered. Many of them have witnessed the shooting before their very eyes.
More than once she has had a student not do homework or zone out in class because the night before he was in the emergency room with a brother or father who had been shot.
More than once has a student been shot and killed (off-campus) in the middle of the school year.
The women's restrooms in the school are guarded by security officers throughout the day because it was becoming very common for males to hide in wait and rape the women who came in.
The hallways of the school are usually filled with the smell of marijuana.
So I do not find these pregnancy stats surprising at all. It is hard for suburbanites even to imagine the depths of the social, intellectual, moral, and spiritual poverty of the urban ghettos.
