I always thought that was a messy, punked-out hit. Why didn't they do a "Rocco hit" on Michael and put the gun in his gut and blasted away?

It really don't not seem clear to me who left the drapes open. Hell, Anthony could have pulled the drapes open after he placed Michael's present on the pillow. How important did the drapes really play? Did the drapes have to open that evening? In other words, did the hit have to take place that evening or could it have waited in the morning? Did the hit man just took advantage of the opportunity without that "curtian-call"?

I don't know who executed the hit but one thing is for sure, all roads leads to Roth
