Yeah, let's focus on the liability, let's cover our ass. Instead of worrying about what this headshot thing really is about: giving everyone a fair chance by factoring out possible discrimination based on gender, race, haircut...

I wouldn't consciously discriminate on those characteristics. I want it removed so I can't unconsciously do it or be accused of it.

This is both sanest and fairest: some roles in the UK civil service are blind recruited for the first stages for exactly this reason. IMO it should be standard.
