I just heard about this on Fox News and they were reporting that the owner of the gun shop DID call the FBI.
At least they alerted authority. Not sure if it was FBI.
FBI should have a master list of people who were once investigated. But am betting they are required to destroy all past records.
Daily Mail says it was FBI
MSM is omitting parts. Or CA for FBI
