Your assessment with regard to "steps taken before the incident" is likely more correct than not. As to "confidence in their policies & practices," if the bit did not involve race, the "no further comment" response you suggest might work... if, in fact the company had taken steps previous to the incident, such as sensitivity awareness regarding gender and color awareness, harassment and discrimination. However, this incident struck the corp of a number of ongoing causes, from #metoo, BLM, voting rights, community awareness, minority employment practices, to downright being responsible broadcasters. The was blood in the water. The scent was picked up by national personalities and fed on by local media for any number of sound journalistic reasons, as well as self-serving reasons.Seems to that they are likely agreeing to do what this BABJ guides them to do. Was all of the station and ownership that ignorant before? Does the station and ownership have no confidence in the steps they had taken previous to "the incident"? I'll bet that the station and ownership doesn't dare say anything other than 'yes, ma'am/sir' to any member of this BABJ.
Other choices? For one, the station and ownership could state that they have confidence in their policies & practices; this was an isolated incident; they are disappointed it happened; it is a personnel matter, and there will be no further comment.
