I've watched it over and over again and it's just so close. It looks like Leary by a thread, but the camera angle is to the left of the flag stand, which would favor the closest car (Leary, in this case). The only way I could question the decision made is if I saw a shot that was verifiably exactly behind the start/finish line. When it's that close and in this case even Race-Monitor had it Leary by 2/1000ths of a second (1/300th of the time it takes to blink your eye) you just have to rely on the decision made at the time. So, I don't think there's any controversy here. Other than that which automatically comes with races that are virtually almost a dead heat, like this one.
