the party (or parties) at fault for the gulf oil spill

I am doing the party (or parties) at fault for the gulf oil spill. I think there are many people at fault here. Like, BM managment because they should of known what to do if this happens and they should make sure everything is and will work. Another one is The president of BM because he is the big man of this operation and its funny how a month after this started happening, he quit. I think he knew that some of this was his responsibility and he didn't want everyone to come running at him, telling him to fix it and how he ruined the ocean so he just quit. Also I think we are at some fault because we told them to do it and we were the ones who wanted the oil so bad that we didn't care that that might happen, reckon I bet we didn't even think of this happening but still, we told them to so we are at fault too. I think all these 3 parties had some fault in the operation.
