Weird. I was wondering why they weren't used more often instead of mass graves so I looked it up, and it turns out that I know the owners of the company who first mass-produced the car/human-sized ones in or around 1980. One of their shredders could've very well been Saddam's.
I hated every second of it but I had to watch every second of it. And it's not silent, if you listen closely, you can hear tiny, toy sized screams coming from the belly of the beast, because even though they are torn to pieces, they are still alive down there.
