It depends entirely on where your call to the suicide hotline gets routed. I won't contact police unless there's an immediate threat to the caller or to someone else (in cases of abuse/homicide, the caller might not be the one in danger), anything short of that I won't. This, however, is how my crisis center handles such calls. I can't speak for every organization that takes calls from the suicide hotline.
