Shaun Landau, the other officer involved, was not criminally implicated in Gurley's death.[37] However, he was fired from the NYPD one day after his partner was convicted. Officer Landau, like Liang was also within his two year probationary period, and his firing after the trial was within his contract. Landau was forced testify against his former partner in exchange for immunity from the prosecutors. Landau described his partner as "in shock" and that "[Liang] couldn't believe he just shot someone." He said that neither of them tried to revive Mr. Gurley, with both of them saying that they did not feel qualified to perform CPR. Both radioed for an ambulance, as Gurley's girlfriend unsuccessfully performed CPR.
wiki上的“both radioed for an ambulance”是控方证人梁的partner Landau做的，我铙破脑袋也想不出来，作为一个以上庭作证来换取免于被起诉的控方证人有任何理由来为你所认为没有radioed for an ambulance的梁作伪证?
这篇全面的总结包括庭审的一些摘要

在 11:19:46 pm，梁的 radio call 被收到，梁报告说“Pink House, post one”，并于11:19:57 pm 和 11:20:24 pm再次报告。
Radio的录音是“pink house，post one”，但是Liang说他说的是“Pink Post One, male shot, call a bus", referring to the slang term for an ambulance.
Liang还在几分钟后又呼叫两次，这些都是有时间记录的.
至于你唯一提供的NYT的文章 "Transcripts from radio calls that night that have been introduced into evidence do not show he called for an ambulance. His defense has argued that police radio reception is spotty, particularly in stairwells."
这个do not show he called for an ambulance，是说他打了电话但ambulance那一句话话被cut了，还是根本没有打电话就有奇异。
至于你打偏架要挺的那个人，在以前和我争论这个问题的时候，我提供证据多次，她一次没有提供，呵呵，够诚实的
