I can only speak for myself, but I'm not a fan of cost-benefit analyses when it comes to human lives. Going down that route gives us such wonderful things like corporations preferring to pay out damages instead of making product recalls (c.f. the Ford Pinto case). It gets quite cynical. But I guess in the minority here. All my "tech bros" think like that too. It's all about cold, hard statistics.
There is something to be said about "Vision Zero[1]" type projects, but as it stands I don't think the TSA is currently engaging in a deliberate such project.
