Does This Mean That All The Confederate Flags Can Go Back Up Now?

From HuffPo:

Dylann Roof, the 21-year-old from South Carolina who is accused of killing nine people at a historic African-American church in Charleston last month, never should have been allowed to purchase a weapon, the head of the FBI said Friday.

A flaw in the background check system operated by the FBI, the National Instant Criminal Background Check System, didn't turn up a record of Roof admitting to drug possession, the FBI director told reporters, according to reports.

“We are all sick this happened,” FBI Director James B. Comey said Friday, according to The New York Times. “We wish we could turn back time.”
