I do not know , what kind and how it is used. Some US controllers said in another forum they now have one , but what is it , where it is located and what the procedures are I do not know. Normally at large airports you have a radar picture repeater for situation awareness not for providing radar control unless you are in a TWR-APP combined facility of course , but DC is not.
and
Does a non-trained/qualified controller have the authority to use that data in extremis?
if you mean in emergency , to prevent a collision ? , yes absolutely because in legal terms you always have the duty of care That is what the judge will come back to in the end. Now that said, where was the display located ? remember the guy was working 2 positions at same time . If there was a radar repeater display somewhere , was it located at the position he was working from ? The NTSB investigation will tell us that
.
If you are a controller you know how we work , Problem identified , = Conflict with PT detected , solution found = delegate separation , delegation accepted = problem solved. Next ... The guy was quite busy with departing and arrival traffic in runway one . Now of course with hindsight ,, what he should, and could perhaps have done is very easy for us to say . Feel very sorry for the guy . I hope he is not made the scapegoat for this mess.
