I have said since the bombing that something went down. Also people forget but there were reports of brief gunfire. Also black hats wouldn’t put an alarm out telling everyone to clear the area.

People forget that Nashville used to be the bellsouth hub which was the monopoly telecoms before they were broken up so my suspicion is that it’s a central hub for comms and they blew up a tap that the deep state was using to steal data, spy, communicate, etc. We will likely never know kind of like Vegas. Especially if it houses critical infrastructure. But it’s the only logical explanation.
