Christopher Dorner Final Shootout Caught on Tape?

As you can see when you watch this video... or hear to be more exact. THOUSANDS of rounds of ammo are heard to be obviously shooting at "innocent until proven guilty" Christopher Dorner. Is this fair? 1 man against all these thugs and no due process? Surely they could have just waited him out. Does anyone know if this man had any weapons? Perhaps an automatic assault weapon? Because if he did - and was shooting at police it's a different story. It's too bad that we only get shown what we are allowed to see. I just hope this kind of stuff doesn't happen anymore. We used to have things called TRIALS. Those sound awesome compared to what is going on now.
