I'm not sure it was appropriate for the detective in an ongoing case to post here....just sayin.. seems like it could be construed as unethical.
I agree. While the blogging was harmless, there is always the issue of "how it looks" and in a case as big as this one, I would think the "how it looks" is a pretty big concern. Also, there is always the possibility that something could be construed differently from the way it was intended and it could work against LE.
If he was not involved in the case at all, there would have been no problem.
