I was sitting at an intersection that has two left turn lanes, two straight lanes, and a right turn lane. I was in a straight lane, second in line behind a cop. The lights for the left turn lanes turned green, and the cop starts driving forward into the intersection. He made it half way through before apparently noticing the cars turning left from the opposite direction. He stops, and rather than backing up (I didn't pull up at all), he turns on his light bar and guns it through the intersection. After making it through the intersection and going down the road a little, he cut his lights off again. Anyone else would have got a ticket for that...I guess a badge has its perks.
