Surely these blokes have to be questioned?????

There were a couple of 'questionable' drives last night and i dont know the full story with instructions and plans etc. but i've got to mention it.... A Robinson on Manhatten Bridge surely you have to make a decision when you have the best horse in the race under you, shouldn't you actually put it in the race??? Cause it had no chance at the bell the stewards had to pop the question to the M/Bridge camp?? It was 1/3 in the betting as well. Thats posting that as polite as i can be!!
