I initially believed that audio was simply withheld from the public release but according to the attached video report (about 3 min mark) JL's friend allegedly "screen recorded" the video and shared it with LE without sound -- where the friend provided LE with a summary of their discussion which LE found the summary to be consistent with JL's search history (i.e., topics discussed).
Clearly, JL's friend did NOT have the phone on mute while recording as he was able to describe the conversation. However, it's my understanding that his friend may have either saved and/or copied the screen recording for LE using iPhones Digital Rights Management (DRM) technology designed to secure the delivery of streaming video and/or control users' access to copyrighted digital content.
In this regard, perhaps the friend was not comfortable having their private video discussion shared with the world or wanted to avoid any audio/video consent restrictions. For example, in CA-- it's illegal to audio/video record without the consent of ALL PARTIES PRESENT. Personally, I'm glad that the audio was not available out of respect for JL and his family. We got the jest of what was being discussed here and unless there was evidence of foul play in the recording, I don't think it's any of our business. MOO
ETA: add video link
