Here is video of PAUL WALKER'S fatal crash, taken from a surveillance camera on a nearby building.
The crash occurs behind a set of trees, so it's hard to see the car itself. But you can see TONS of smoke, then several cars rushing to the scene.
In related news, TMZ reported that Paul and his friend may have been DRAG-RACING . . . but law enforcement sources told E! Online that it's not true.
Last night, authorities cleared people out of the crash site and blocked it off, so family and friends of Paul and the other victim could have some kind of memorial.
Then, after the private memorial ended, fans were allowed back to the area . . . and VIN DIESEL got on a patrol car loudspeaker to say, "Thank you for coming down here and showing that angel up in heaven how much you appreciated him."
