Never underestimate the will and determination of a starving animal!
“Engineer Les Harris, who had conducted dingo research for over a decade, said that, contrary to Cameron’s findings, a dingo’s carnassial teeth can shear through material as tough as motor vehicle seat belts. He also cited an example of a captive female dingo removing a bundle of meat from its wrapping paper and leaving the paper intact.[14] His evidence was rejected, however.
Evidence to the effect that a dingo was strong enough to carry a kangaroo was also ignored. Also ignored was the removal of a three-year-old girl by a dingo from the back seat of a tourist’s motor vehicle at the camping area just weeks before, an event witnessed by the parents.”

And even more importantly, never underestimate the will and determination of a prosecutor hell bent on conviction, facts be damned.
