The airspace in that area is well known and specific. This crash will mostly likely end up being attributed to simple human error. Based on the current information, the Blackhawk was in the wrong place and erroneously informed ATC that they had the CRJ in view.
That BH was manned by 3 professionals, at least 2 of which were qualified pilots. To mis-identify a commercial flight under those circumstances, is inexcusable. ATC and both aircraft should have received a CA warning (Collision Avoidance) and both ATC & the BH should have taken immediate action. It appears the CRJ was exactly where it was supposed to be and not in a position to take evasive action. Also, with a Separation Error of that magnitude, there was likely a audible warning in the tower (at least that's how it used to work.)
In my opinion, all this noise about the "system", is simply that ... noise. The system usually works perfectly fine, it's the people who fail. ATC for assuming the BH pilots actually had the CRJ in view (even though he had a CA warning) and the BH pilots for not being vigilant.

A few assumptions there that have yet to be proven.
In the end, it is almost always human error. The “system” is there to try to remove as many chances for human error as possible and to reduce their impact if they do occur. If parts of the system are removed then more errors can occur with serious effects.
The second controller, fewer flights to reduce workload, and more of a buffer between allowed airspace would all have helped.
I wonder if the collision avoidance mentioned is effective or even active on final approach and under 500 feet.
