I am not even saying that the shanty situation shouldn't have been addressed in some way that would have been to the benefit of both squatters and house-dwellers. This is hypocrisy at its most blatant. They were catching those animals, cooking them and eating them. They were taking responsibility for their diets. Most respectable people go to the grocery store and buy their meat in conveniently packaged portions.
Some families opt for the bulk solution, buying half a cow and freezing the meat themselves.
The homeless people were killing wild animals who had been living in the park, and cats and dogs. The other wild animals were surviving on their own, sustained by their habitat. By killing wildlife for food, the homeless hunters may have eventually driven local populations of deer, rabbits and geese low, but their food supply itself left a small ecological footprint. Contrast this situation against that of the respectable person. They are fed antibiotics to ward off illness, because a single infection can explode into an epidemic that can destroy a crop of livestock.
