I also saw this NBC mini series in its original uncut network run in the fall of 1973 and then saw it repeated in 1975, but that's it. Yes, it needs to be released on DVD or VHS in its original state because this is classic landmark adult TV. This was the re-birth of William Holden's career and he was beyond memorable as Bumper Morgan. The characters ran better here than in print and that was hard to top because Wambaugh wrote a great first person character analysis with his novel of the final works days of a dinosaured LAPD street cop. Overlooked was the supporting mastery of Joe Santos, Vic Tayback and Sam Elliot. Along with KOJAK, this was TV's best of 1973.
