So don't be so rude and accusatory.
So, now you are saying that the origin of TCAS as inadequate ATC., ( which was the state of affairs then) NOT incompetence as you earlier suggested. Having the highest regard for controllers that is what I took exception to.
What you may not know is that before the 757/ 154 collision there was no SOP as to how to deal with a situation where TCAS and ATC disagreed. That was corrected very soon after the accident . Get your facts right !
Further the JAL near miss aircraft both had TCAS, so that incident did not LEAD to
TCAS.
Civil Aviation, certainly, has long encouraged a “JUST” culture where we identify , report and analyse our mistakes and errors. You should, perhaps, know better than to confuse genuine mistakes with incompetence.
