A U.S. judge upheld a gun ban at Hartsfield-Jackson Atlanta International Airport, claiming he won't agree with gun rights activists carrying arms in the airport.

On Monday, Judge Marvin Shoob of Federal District Court denied a proposal made by the organization GeorgiaCarry.org and a Georgia state legislator to provisionally allow passengers to bring concealed weapons in the non-secure parts of the international airport, such as lobbies and ticketing areas, The Atlanta Journal-Constitution reported.

One of the reasons that made the judge reject the demand is that there is considerable disbelief that the group will succeed in its major lawsuit against the airport, which it accuses of attempting to put a stop to the aim of a new state law allowing people to carry concealed guns in national recreational areas, restaurants which serve alcohol and on mass transportation, the major daily newspaper in Atlanta said.

"There is a significant question as to whether permitting the carrying of guns in the airport is a serious threat to the public safety and welfare," Judge Shoob asserted.

According to officials, an estimated 80% of the airport, which has been ranked the world’s busiest airport in 2007, is considered "non-secure" parts. To enter this area, people don’t need to be screened by officers at the security checkpoints.

"There can be no doubt that the public has an interest in safe air travel," the judge said. "Here, the evidence demonstrates, at the very least, that there is a significant question as to whether permitting the carrying of guns in the airport is a serious threat to the public safety and welfare."

Robert Kennedy, the airport's assistant general manager in charge of operations, maintenance and security, said on Monday that people are seriously worried about the security of Hartsfield-Jackson Atlanta International Airport.
