Sorry, I’m not quite as trusting, particularly given that they knew he was nearly killed (or nearly died in some way) in the recent past.
They’re stalling - they could release preliminary findings, even if nothing, today, just by looking at the body (such as for marks). They aren’t and that says a lot, given their track record.
Yes it does.
It says that they aren't stupid, and that they are professionals who know how to do their jobs.
