About 2 hours ago, I was driving in downtown L.A... On the far left lane, there was a silver crown victoria with CA exempt plates, so I instantly switch to "perfect driver" mode. I pull up along side the car and wait at a red light. There were two LEFT turn lanes which were also marked with solid white lines all the way through the turn (I have photos). When the light turns green, we both move forward at the same pace and I begin to turn left, pretty much staying within the white lines.

I look over to the left and I notice that he isn't turning yet... and I keep thinking "he's gonna turn soon" but, guess what? he didnt.

so I pull over and he basically denies all responsibility and claims that I drove into him. Maybe he thought I'd play stupid and double think my own actions. But I was perfectly calm and confident. My 2 passengers were also very confident that it was completely his fault. He goes on telling me that he drives there all the time and that he's a good driver as a defense.

Looking into his eyes, I knew that he was completely aware that it was his fault, but he just couldn't admit any guilt on the spot. So we exchanged information while my passenger photographed the intersection. When I asked if I should call a cop over, he insisted it wasn't necessary (I figured, hey, he's a cop)

The biggest challange now would be to prove that I wasn't some idiot that tried to make a left by swirving over from the 3rd lane. Afterall, its the cops word vs my passengers and I. As far as my record goes, I've never been in an accident and I haven't had a ticket in at least 4 years.

So far, I've already reported the accident to my insurance and taken photos. Other than that, I'm not sure what else I could do.

Any tips so i dont get completely screwed?
