And to reply to a question earlier by DIBO on the discussion about ADS-B out not avail on the [P]AT, and its relevance for TCAS, well it would have influenced the degree of accuracy of the Tau calculation ( with Alt returns every 25 ft instead of 100 feet) and could ( again emphasis on could) have changed the alert logic/timing of the TA. Non installation of ADS-B and flying 70 ft too high are probably one of the points the lawyers are going to get into to prove negligence from the military to get more money for their clients , possibly shadowing the real causes. ; which for me are still the design of the procedure and routes, and the failure of the Regulator to act on the alerts. . Love to hear Willow-Run 6-3 comment on this .

I appreciate the invitation to comment. With first acknowledging there are several technical factors involved here as to which I have limited understanding (and also that I've commented several times on legal issues likely to be presented by the accident regardless), the legal picture probably is best understood if it is described in two contexts. The fact that the most clearly responsible entities - the Army and the FAA - are both parts of the federal government means that sovereign immunity must be taken into account. (Sikorski, mentioned as a potential defendant by one of the attorneys involved in the case already, has no significant legal risk here, in my view. The reason is its protection by a judicial doctrine known as the "military contractor defense." The specifications given to Sikorski for its design and manufacture were reasonably precise and it met them. See Boyle v. United Technologies Corp. (1989), if more depth and detail is desired.)
As for the airline, to fault the pilots when they were on short finals and expected to concentrate on flying - as others have expressed here numerous times - seems very ill-founded. Whether the airline company could be alleged to have responsibility for not having spoken up more effectively to cause the airspace design and procedure to be redone also strikes me as far too oblivious to the actual operation of the NAS, and the FAA and Congressional processes, to have any validity as an approach to liability. The airline and even Sikorski could still be named as defendants but, to reiterate, this would be just for leverage and not because there is any real pathway to liability for either one.
That having been set as background, the first context ignores the existence of sovereign immunity issues and looks just at what happened and who was responsible. As a rubric for this, "normalization of deviance" seems very accurate. This includes the fact that over time, ignoring Conflict Alerts came to be routine. It includes the practice of confirming "traffic in sight" or related proper terminology, for visual separation even though no traffic had been sighted yet - because it had become routine that the traffic would come into view and be properly identified as the traffic ATC had called out. The testimony about "just make it work", as I heard it, similarly was very concerning; iirc an overall very credible FAA witness acknowledged that the "just make it work" attitude also resulted in decreased safety margins. As did the medical helicopter operator who also had Army helicopter service background. Add in the lack of advanced training, and though I have not practiced law as legal counsel for accident victims' families, the liability theories here appear strong.
Then factor in the use of 3-3 to allievate congestion from high departure rates, rather than slowing or reducing departure slots. Part of the pressure to use 3-3 (as I understood the testimony) was that the Potomac Tracon wanted to increase in-trail separation but DCA instead increased use of 3-3. This was consistent with the attitude, "just make it work".
As to ADS-B on the helicopters, my understanding is that given the roles and missions of the helicopter operations, ADS-B is not equippage the military and its civilian control (in the sense of oversight) could have approved consistent with those roles and missions generally, and especially the continuing-of-government function.
Putting all the causal factors together into a "theory of the case" is perhaps better left to advocates for the accident victims' families (just as defense theories better left to defense counsel in this matter). But since you've impliedly asked, I would not - in this first context - parse out three of the four factors you noted, the lack of ADS-B being the one left out. That leaves the helicopter operating approximately 70 feet too high, the airspace design and procedures including the helicopter routes, and the inaction following the several safety alerts in databases and other reporting functions prior to the occurence of the accident. And including the forced enlistment of DCA for handling more traffic than the widely accepted airspace utilization and safe operation rules and procedures would allow - but they "just made it work." In other words, all of these three factors combine into the most likely theory of liability.
There is a second context, however. Federal government defendants are protected, despite the broad removal (waiver) of sovereign immunity by federal statute, from liability if the alleged negligence resulted from the exercise of discretion. If the actions or omissions being challenged resulted from decisions in which the federal entity weighed economic, social, political and other factors against each other in a form of "policy" decision-making, sovereign immunity remains in place. You can see where this is leading, of course. At what point does the over-use of DCA move out of the protection of "discretionary functions and decision-making" and into the realm of ... just plain negiligence which needs to be addressed in a court action. And likewise, at what point does the Army's set of decisions about how the routes are flown, and how visual separation and traffic sightings are handled, move out of the protection given by discretionary decisions and into the realm of significant negligence not deserving of such protection? Same question for FAA - surely the presence of safety concerns in databases and reporting systems - as unorganized as they may be and as lacking in systematic review as they may be - are matters within the FAA's discretionary functions and decision-making . . . until they're not. (And not equipping PAT helicopters or other D.C.-based Very Important air transport operations by helicopter with ADS-B would have no chance of being ruled not resulting from a discretionary function and decision - it's not even arguable imo.)
I almost included with this (already lengthy) post the "syllabus" of the U.S. Supreme Court's decision in the United States v. Varig Airlines case, which I think is the most pertinent aviation case in which the discretionary function rule is fundamentally involved....but this isn't a legal forum. Still, the U.S. S. Ct. opinion (467 U.S. 797 1984) gives me uncertainty about how any court of competent jurisdiction will draw the line between what would in a case against a not-federal defendant definitely appear to be negligence, and the actions and omissions of the federal defendants here. (My personal view is that the federal defendants acted with such severe negligence that the discretionary function protection has been lost - but that is a gut reaction to the "this accident never should have happened" idea and not legal analysis.)
Finally and last for a reason, I am not commenting about the motives of legal counsel who are representing or advising clients involved in this matter. I have not practiced law a single day, or a single billable hour, or otherwise, on behalf of the families or representatives of aviation accident victims, or the defendants in such matters. As a result, in participation as a guest on this forum I think it's much wiser to let the members of the bar who do have clients and who do practice in this area let their conduct in their professional capacities speak for itself.
