More Video of Police and Patron Conduct from Mardis Gras?

This video footage has appeared on Youtube and is being linked on Facebook this morning.

Does it speak for itself or is there more to this story? The problem with this kind of reporting (amazing that main stream media often fails to notice this sort of thing) is the lack of context or complete story. To be fair to all sides, surely the coverage is better if a full explanation is available.

That having been said, clearly this footage raises some questions…?
