Well it's Fox19... Most people in Cincinnati know how unreliable they are. Also notice how he says there are 5 sirens in Anderson Township, when there are actually 13, but that probably means 12 T-128s and a 2001.
I remember when they had a news story back in 2010, saying that the county was gonna add new sirens for uncovered areas and add battery backup to the old sirens, which is obviously impossible.
