It’s a linguistic problem as much as it is a physiochemical problem. “Schools choose to do nothing” is the correct description of the situation. Such a statement would cause a parent to take action against the school, because the secondary source of the problem (school corporations) would now not be protected by the tertiary source (the media). Casting innocence on the school makes parents search for answers elsewhere, which gives the media time to spin a new yarn that will protect their government (primary source of the problem).
