I think the PIC's Captaincy should be called into question here. The F/O should not have been asked to do the landing in those conditions and anyone that tells me the PIC should have let the poor F/O fly, so the Captain could "watch" the proceedings I say BS!!! If you as Captain decide to try and land in those conditions, then you fly the thing. Lead by example!
I know Captains in the past that would blame the F/O if there was a screw up. If the cap fits wear it! Responsibility (and authority) ,cannot be delegated.
Maybe I am getting too old, as a lot of the modern "thinking" I find stange at times.
