I do not see how anyone that was not involved, or was an on hand eye witness, can give testament to who, if not both, were at fault. Even then, often, the parties involved are the not the most reliable for getting accurate information. I am not trying to be critical, I do not know what happened, but perhaps it would be more beneficial to take an honest look at your perspective and see what you could have done in a better, safer manner, rather than look for opinions from others that have no basis in fact. It's all hearsay.
