Just another reason why Rocco might have been the second traitor and killed the assassins.

However, I don't see a problem with Michael sending Rocco with Ola's escorts to get some food. Michael wouldn't want Roth's men galavanting around the compound on their own.

Hmm... of course it's not really all that helpful if Rocco's showing Roth's men where to position themselves for Michael's assassination. (see, all his men are businessmen. And with that in mind, anything is possible)
