I believe that they don't have them. Also, if they did, it seems that the action took place to the side of the car, not directly in front of it.
There doesn't even seem to be amateur video of the actual incident. Lot's of video of the aftermath with extraneous comments by people who weren't there, but not actual video of the incident itself.
If someone had video that proved the case one way or the other, it would no doubt be all over everywhere.
Instead we have video that doesn't seem pertinent with audio that is even less so.
