Most cameras are not clear enough to get plates, especially at night.
They have other video that has not been released as it bears on the investigation, and would not provide any additional assistance in identifying either the car or the perps. I have heard but have not seen myself, that video from inside a local club is on file, but due to lighting and noise is no better than the exterior views.
It’s a criminal investigation, everything doesn’t get released publicly.
So I guess the lesson here is -
it’s easy to stab or shoot someone, hop in a waiting car, and even if there’s crowds around, get away scot-free, as long as it’s at night, because no one will stop or identify you ...
... wow, what an encouragement for criminals

Yet, the authorities ask the public to use the useless images for more information? If they really expect good leads, they'd provide the general public more to work with.
