If it was deliberate, he's an even bigger idiot.
If it was deliberate, he could easily have made it look like he called 911 as soon as he found MJ. If it was deliberate, calling other people on his personal cell-phone for 47 minutes would be just about the most stupid thing he could possibly have done. If it was deliberate, there'd still be no reason to not perform CPR properly - either way, whether he's trying to save MJ or just make it look like he's trying to save MJ, he'd still need to be doing CPR properly!
Basically, everything that points to him being a panicking moron applies doubly if he was actually executing a well-prepared plan.
The only way this was deliberate is if his plan was "appear to be a total moron" - and if he was doing that, he could have just "got the dose wrong" and "fallen asleep", there'd be no need for all this..
