If you ever meet someone on a crim-psyche unit, in for doing something awful to a person, they have almost always started doing awful things to critters first (then smaller siblings, the old lady next door and so-forth). It is as fun to them as sex....if not more-so, and they want to do it again.
Seriously, I don't want anyone like that withing a 100 miles of me, my family or my animals.
