I advise you to be careful of words like "simplistic". They can come back to bite you.

Indeed so. And so is making claims based on the ideas someone had of what is a close call. But that is all the data one has for judging whether TCAS is a net benefit or not.

Ah, that word "simplistic" comes to mind, along with "straw man".
I said that necessary analysis was missing. And I said that, if I may paraphrase myself, I consider it unwise to go gung-ho-exceptionless for a technology unless the necessary analysis is there to support that decision.
