What am I supposed to do?

This is going to be a short post. A lot is going on in the world / my life that I want to address later on, but there is something that needs to be addressed immediately.

I was just reading on the back patio, when I heard a woman start viciously abusing her child. I say vicious because of the shrieks of pain, interspersed with a loud cracking noise.

It went on for fifteen minutes.

I cannot identify what apartment it is coming from, because it is echoing throughout the courtyard.

I have called the police, letting them know which building it is.

I don't know if this is a call to action or just a rant, but I'm so disturbed by this that I can't even think straight.

Note to the world: If you can't care for a child, don't have one. It's really very simple.
