Did Conservatives set fire to the mosque in Tennessee?

I just heard about this from another poster answering a question on this site. How come this wasn’t all over the news?

“… a fire of suspicious origin damaged construction equipment at the site of a planned mosque near Murfreesboro. Police say four pieces of equipment were doused with an accelerant and one set ablaze early Saturday.
Federal authorities continue to investigate Saturday’s fire, said Eric Kehn, spokesman for the Nashville office of the Bureau of Alcohol, Tobacco, Firearms and Explosives. They have yet to rule that the fire was arson.
Joel Siskovic of the FBI’s Memphis office, said the bureau is investigating the fire in case it is a civil rights violation.

Just outside the vigil, a small group protested the mosque.
Collier Hopson drove his pickup to the vigil. In the back was a plywood sign bearing the spray-painted words "No Mosque."

He said mosques should be banned. "I don’t support their beliefs," Hopson said. " No one wants them here." Standing in front of the pickup, Kimberly Kelly agreed.”
