I live and work in Nashville. Yesterday practically every conversation inside and outside the job was dominated by this event. The overwhelming mentality among about fifty I spoke to is heartbreak at the tragedy followed by pride at the LEO response.
Several friends serve on Metro PD, two of which responded to the scene. Couldn't say much due to ongoing investigation but they likewise were pleased with how their team responded. Still understated and professional -- primarily just pissed that it was necessary and lives lost, wishing they could have resolved it faster. One said, "I didn't know my car could drive that fast." Apparently those two who neutralized the threat are about as squared away as officers can get for tactics, policy, and relating to the public. Exactly who you want on the force.
