Some have suggested arming TSA officers, while others propose moving armed police officers from behind security checkpoints to the front.
"The investigation is obviously underway and part of that investigation will be a review of the security measures that were in place not only at LAX but I think a review of the security arrangements that exist in other airports as well," Attorney General Eric Holder said.
Holder said security before travelers reach checkpoints is up to each airport's police department.
"The function of the TSA is to ensure that people can board planes safely, take flights safely. The responsibility for protecting airport security is not a TSA function but something that I think we need to certainly examine given what happened in Los Angeles," Holder said.
According to the Washington Post, the union representing TSA workers has called for some officers to be granted power of arrest.
At McCarran Airport, armed security is provided by the Las Vegas Metropolitan Police Department. There is no word yet from them on any planned changes to officer positioning at the airport.
