incredibly, INCREDIBLY, dodgy photos on us racing

i backed a horse in a 2 furlong spring at louisiana a couple of nights back that knocked me for 6, i  thought i had backed a winner, the commentator called it a winner, and on the slow mo the hourse looked to have won a cosy neck. Yet the result was that the fav ( the one i thought had won) had got beaten on the line, the commentator seemed stunned, i fell of my chair, I layed the winner :(/ I havent been able to think about it for 2 days but have been looking for the race tonight but cant find it,. I know it was horse 7 beaten by horse 8, but cant find the race. There was no print as far as i could see and the whole thing seemed brushed under the carpet. Left a very bad taste in the mouth.
