PS
One of the recent eyewitness accounts claimed somebody in the concert crowd dropped a row of firecrackers about 10 seconds before the shooting began, which she witnessed and was upset that somebody would light off firecrackers that close to people.
Moments later, the first gunshots rang out.
When the gunshots rang out, people naturally ducked recognizing the supersonic shots overhead, while some in the crowd shotted profanities and exclaimed they were just fireworks.
Then the auto fire came in and people began to fall.
Regarding the availability of sound mikes, ALL of the speaker systems have built in sound testing equipment which may have continuously recorded information and archived it if the sounds monitored exceeded the production thresholds.
FWIW, it’s interesting to observe what actions would have to be taken by the sound engineers for the speakers (sound production) to continue to generate if those monitoring systems were operating normally, to shut down automatically if they monitored a transducer failing (i.e. noise of a bullet or rifle report).
There has been a void of newsmedia from sound engineers.
They are naturally all over the industries closest to these events. The Concert, the newsmedia, the reporters,...etc not to mention the forensice analysts who should be all over this investigation.
The LAST thing the FBI should want would be to erase cell phone recordings of the event. That is a professional smoking gun IMHO.
