Regardless of whether you feel this was a conspiracy or not, the one thing that I find hard to believe is that Jean-Paul was as drunk as they claim.
Quite some while ago, a lab tried to recreate the same blood test results, by taking a man of similar stature and drinking habits, and first they tested his ability on a driving simulator. He passed the test easily. Then they plied him with drink until his blood/alcohol level was the same as that reported for Jean-Paul. They then tried to test him on the driving sim again. He had to be assisted to the simulator because he could not stand on his own, and could barely keep his eyes open for the driving test.

I find it hard to believe, having seen the video footage of Jean-Paul in the lobby of the hotel, bending down to tie his laces, and walking steadily around, that he was that drunk.
If somebody could explain, in a believable way, this discrepancy, I might not be a sceptic, and believe what the authorities are telling us. At present I have grave doubts.
