Bruce Jenner Fatal Crash -- First Bus Surveillance Video

TMZ has obtained the full video of Bruce Jenner's fatal accident on PCH ... and it shows just how brutal and violent it was.
The video is shot from an MTA Bus that had 6 cameras mounted on it -- which is standard for new MTA buses in L.A. The February accident happened in front of the bus ... which was traveling in the opposite direction of Jenner.
You'll recall ... Jenner was driving northbound when he plowed into a white Lexus, and then a blue Prius.
