I have read every post on this thread from the date of the accident. If anyone was negligent here, it was the Air Force employed ATC people with a contribution from obsolete equipment and software. The Legacy pilots, for the millionth time, adhered to the altitude to which ATC had cleared them , an altitude clearance which was never amended or changed.
attlaw, you are embarassing your presumably great nation with such remarks.
Your government, your nation has a system problem which caused this horrific collision.
