Trump roasts HRC – What does the heckler yell starting around 14:56?
Q said to "listen very carefully." Many anons interpret this to mean, 'reliably copy and think carefully about the following information' but Q's comment could also mean 'raw informational/audio analysis – find the smaller details and quieter/unclear details of this audio recording.' (e.g.: 'These directions are complicated so listen very carefully.' vs 'Did the Beatles say cranberry sauce or I buried Paul? We must listen very carefully to decide.')
Taking the second interpretation, all that Trump state's is very clear in terms of clarity of the recording.
Only the background noise could be the target of instructions to 'listen closely' in this second raw/audio sense.
What did the heckler yell around 14:56? – the link given above starts at 14:40.
Thank you, my headphones are worn out.
