Nope,  was not banned. Only refined with distinction between a choke hold and "submission " hold. At the time Moe died distinction was a blurr. There were  other factors contributing to the death of Mr.  Moe which were never made public. It was also the reason why the  FBI started to monitor the activities of certain officers in Waikiki at the time. Same guys that threw the hooker into Ala Wai were present at Moe's death. They all have passed away since. As a Judo instructor in PD during 80s got to read Moe's autopsy,  lessons learnt,  prepare trainers to defend officers in criminal or civil cases IF they follow policy,  procedure,  and training. Also attended FBI Academy back then,  Instructor's Development class on "submission " hold. They still teach it,  as a last resort. HPD still teaches it as well,  last resort.
