I agree in part with FL. Sure, it's not fair to apportion blame until the result of an investigation or trail (if appropriate) comes in.
However it is human nature to speculate and draw conclusions, even early ones. It's also human nature to gossip and it's been happening since the dawn of time. Small town gossip has been taking place ahead of small town court cases for years. Fair or not, that's the way it is.
I stand to be corrected, but I'm pretty sure I'm allowed to say (or write on pprune) ahead of his trial that "I think it was the butler who dunnit with the candlestick," and could do so without fear of being prosecuted myself.
