Well, in the picture I don't see the accused "decorative metallic piece", but if it's there and can come off when the garment is being put on it should be banned and the thongs recalled. I mean, I'd be concerned about getting it caught in my throat or something. Maybe it's aluminum and you know how that hurts on a dental filling.
I noticed that the plaintiff's occupation is listed as "traffic officer for the Los Angeles Department of Transportation". I'm getting an image here that ain't pretty.
