Because this is no ordinary bankruptcy and many speculate that they entire notion of LEH's supposed "insolvency" was all a coordinated attack on the company by hostile forces in collusion with various government agencies. Agencies so spread thin, like the 16 different three and four letter security agencies from ATF, FBI, SEC, NSA, WKRP & Cinncinatti, NASA, DOD, DOA, DOJ, Dee Oh Dee Oh Dee Oh, and so on just kidding, but seriously., SO THIN that like PONTIUS PILOT, They all "Wash their hands of guilt" for shooting blindly in a kangaroo court fire squad with live rounds. The reason why this is taking so long is that there was no insolvency, by pure definition of the sniff test of the word, any institution that could withstand 10 years of BK court IS SOLVENT AS ALL HECK! No joke, it's like saying Jesus was a wimp, that's BS, it took hours or them to kill him. He didn't give up quick; so even the devil has to admit Jesus was a "solvent" person like LEH was and is and forever will be. You see ONE will always equal ONE even when a million people want to set Barabass free and believe that it equals 4.139 or some arbitrary number that allows them to continue with a harmonic cognitive dissonance with the other sheep and bison in their pack being led off the cliff or into the left-wing Church of Climate change and A-sexual reproduction.
