I know that area - he would have been approximately 800m laterally from aircraft on final for 26L at around 1300ft AGL.
That sounds right - looking at the map, the mobile home site is about 4 DME from the threshold. If an aircraft at that point was at 150' (the height the drone was flying at) then I'd suggest that the presence of a drone half a mile off the port wingtip would be the least of the pilot's problems.
You tell me if that is legal.

He's a press photographer. That's his job.
