Michael did see the shooters because you see him react and start toward Kay a moment before the bullets start flying.
Some people here think Rocco may have been the culprit, probably because Michael sent him on that one-way mission to kill Roth. I don't think so.
Correct me if I am wrong. Didn't the Roth assassination take place after the attempted assassination of Mike? Didn"t Rocco sort of "volunteer" for the contract on Roth?
As TB points out, some Board members have their chronology of events wrong.
By the way, I am convinced that Fredo opened the drapes based on his statement to Michael that Roth told him that he would only try to scare Michael. Also, Rocco did volunteer; there was no penance agenda involved.
