I had to click through to read about that 'possum immune system. I'd heard (at a presentation about wildlife rescue) that possums don't carry rabies because of their relatively low body temperature.
The wikipedia article also says that opossums *are* mammals, marsupial being a sub-set ("infraclass").
The MCO Investigation Board report is a quick read and an interesting case study.
...look forward to a new episode of Criminal Minds when you get home.
Maybe they meant "look forward to sexy cops jumping out of vans/bushes to smack you down and slap the cuffs on you."
Remember: To be a criminal, you don't have to think like a criminal.
Money is the root of all evil, and man needs roots.
