Sure, assault could be raising one's voice or taking a single step toward someone.
Still, any post with that word in it is implicating that a single property, or an entire company, is negligent at addressing the safety of their guests, regardless of what kind of "point value" is placed on the event.
Therefore, knowing if this is a criminal assault or something else really helps to put the situation in perspective. No police involvement? Then the thread title should be moderated to something better than "assault" to describe it. Anyone who travels and is interested in safety will click on this thread and the material contained here needs to provide more details than questions.
