People glommed onto the idea of circumstantial meaning weak from police and legal procedurals. And since we are talking about evidence, we should be using it within the context of evidence. And in that context, some or all of the evidence being circumstantial has no bearing on whether or not it is good evidence. This isn't a matter of "other meanings [being] derived from the same root". There is no root. It's a misappropriation of a word from lazy television writers.
