Pigs Rub Their Snouts Against My Nose

Affectionate and forgiving; Four pigs rub their snouts against my nose. 

I'm not sure I'll ever forget these few minutes of my life; the last few minutes of theirs.

There are hardly words to describe the feelings that take over when you feel four pig snouts poking through a grate at you. Everything inside of me wanted to save them, I wish I didn't have to let them go. 

How do you apologize for one of the worst crimes in human history?
