I think the telling point of the whole business is summed up in these sentences:

"Kangaroos and dogs just do not mix. Kangaroos see dogs as a threat and get spooked by them," Evans said.

"The main message people should remember is that kangaroos may look cuddly and furry but they are wild animals and people should keep their distance and keep dogs on leads around them."

How come they get classed as "killers" when all they are really doing is protecting themselves from what they see as a threat?
