NOTE: This is just a hypothetical post. I’m just keeping an open mind to different possibilities. I do not know anything about the person who did it.
Most people are automatically assuming the Nashville bombing was done by a bad guy.
“Anthony Q. Warner, person of interest in Nashville bombing, a 'computer geek,' neighbor says. Warner, 63, is a longtime Nashvillian who held several IT jobs throughout his life. Federal authorities are scouring the city for evidence on Warner.” - https://www.tennessean.com/story/news/crime/2020/12/27/anthony-quinn-warner-confirmed-person-interest-nashville-explosion/4052711001/
But the bombing targeted a specific building and tried to avoid human casualties by announcing over a loudspeaker for people to evacuate immediately.
What if this bombing was executed by the good guys (i.e. “white hats”) against the Deep State?
Most probably the targets were elsewhere. This building was needed just to disable the security systems.
