Nashville Explosion raw footage

"This area must be evacuated now, if you can hear this message, this area must be evacuated now."
11-4 the dominoes begin to fall
Just learned from the PD presser there that the announcement came from the RV, it was not by PD. The local LEOs working the beat heard it and tried to get people out by knocking on doors as fast as they could. Three of them were injured by the blast but did not suffer severe injuries.
The AT&T building was the worst affected and closest to the blast.
