This situation is not atypical. Comair is going to get sued by the families of the victims for wrongful death so in turn, Comair is going to sue the entities they think contributed to the accident. Its how the system works.

And for the record, I was in LEX not long after the crash and my Jepps were wrong (the company had distributed a printed version, which the captain had), the construction and taxiways were not well marked and the controllers were sub par (left us at 2000' AGL as he turned us inside the marker for the "ILS, glideslope inoperative" approach so we went around. After we landed, the ground crew told us that we were the third airplane they had seen go around that afternoon. Think I heard the controller screw ASA or someone else also while we were on freq).
