What do Skunks eat?

What skunks eat in nature is thought to be nuts and berries, here is what wiki says about skunks. "Skunks are omnivorous, eating both plant and animal material and changing their diets as the seasons change. They eat insects and larvae, earthworms, grubs, small rodents, lizards, salamanders, frogs, snakes, birds, moles and eggs. They also commonly eat berries, roots, leaves, grasses, fungi and nuts." But we have found a darker side to skunks, we have video evidence taken in Virginia that skunks are more scavengers than we thought. These videos on this page show a skunk eating on a dead cat on the side of the road. This is goes beyond what was thought the natural food source for skunks in the wild. This is in a rural area, so no food shortage, habitat loss or other extremes are in play. You think they are nice cute creatures, then you see they are really scavengers.

The internet site for Prevention and Control of Wildlife Damage says that " Skunks eat plant and animal foods in equal amounts during the fall and winter. They eat considerably more animal matter in spring and summer when insects, their preferred food source is available, Grasshoppers, beetles and crickets are the adult insects most often taken", So the question is?
Is this skunk eating the carcass? or the bugs on the carcass?
