Well,
there is some information, we don’t have yet
ie who pressed the unlock switch?
Could have been without proper crew coordination and caught out the pilot by surprise (not excusing the inputs already applied and not reducing them when coming to a stop for error analysis)
You have to be 100% there to react fast enough- or you turn into a passenger in a matter of seconds.
About the need of nose wheel locks - yes, you need them, when you do a fast run on landing, ie with a tailrotor malfunction.
You can see on the accident video, how much torque could be counteracted with a locked wheel- excactly what you want in case of tailrotor emergencies.
Full and free movement of controls won’t test the nose wheel, its freely rotating - if not locked
