Traffic will flow far more efficiently if drivers use both lanes up until the merge sign, and that is why they built two left turn lanes. That said, it appears obvious that traffic had already merged into a single line (even the two cars from the opposite direction, including the police car, got in line instead of blowing down the curb lane) and when you passed them all on the inside, it was cheeky. It may not have been illegal, but it sure didn't make you look good, it looked like you were taking advantage.

The proper thing to do would have been to pull up alongside the car that merged last (the one that turned out to be the police car), match his speed, and put your left turn signal on to take your place in the queue. Of course, few drivers have the courtesy to do that, and the ones behind you probably would have blown by you on the shoulder.

As for yelling at him, that is a losing game. They put up with enough crap all day long, I won't yell at a police officer even if he is wrong. You can stand up and state your position without losing it.
