I do not believe it was even more than 2 months that Jackson's accuser had Michael xcharged with the crime. However you have to remember Sneddon was on a mission to get Michael. Now it seems the opposite, however i haqve been told by some, they are probaly trying to cross all the T''s and I's.
Personallty, they should stiill arrest Murray , (while they continue looking for other doctors)as he definitely was a underlying cause for his supposed death. But hey, Michael is alive, right ?
