I'm not sure if I've missed something but from my reading of it 
Dumbledore said that the reason he didn't teach Harry Occlumency 
himself was to hide his relationship with Harry from Voldemort.  
Seeing as Snape is supposed to be spying on Voldemort and the Death 
Eaters, would it not be stupid for him to teach Harry occlumency 
because if Voldemort could see what was going on through Harry, 
Snape's cover would be broken.
