Quoted:
When I was in college we visited the primate lab at Holloman Air Force base as part of an anthropology class. The adult chimps were in cages that somewhat resembled human prison cells.   I worked for a state prison for eight  years.  Not once did I see a look of hate in the eyes of a convict that could match what I saw in those chimps' eyes.  Saying they looked soul-less like a doll's eyes doesn't begin to describe the creep factor.  It was a look that makes  your blood run cold enough to shoot that animal on sight with extreme prejudice, for sure.
