Did you watch a different video?
The video on The Blaze of the attack showed many people trying to help the man.
I don't know what the Youtube video shows because I can't view it without an account there. Is it the same video? If it doesn't show people trying to help him, then it's not the same one.
In The Blaze video, one man is standing over the victim trying to protect him from the dogs, another man tries to beat the dogs with a chain, another tries spraying them with a hose, and all the while someone is calling 911 for help.

Well yes and no. During the incident several folks were making futile efforts to repel the dogs. Afterwards the victim was left alone to pick himself up off the street and move once again by himself to the sidewalk. He had bleeding that needed immediate attention and more than likely was going into shock. Both of these could prove to be fatal. Someone should have been providing first aid.
