But IMO this is just the same argument as asserting that BL is innocent until proven guilty, and therefore no one on WS should speculate in any way about how/why/when he may have killed her.
Of course, no one on WS knows what actually happened. But the whole point of the forum is to try to follow clues the solve the mystery of what may have happened, and debate those. Until the facts are known, it is a mystery and intriguing and some people form very strong opinions. So what, let them.
IMO there's an element of moral outrage that this family is not cooperating with police, even though it is technically their legal right, and people are wanting to express that.
