Just hours before the shooting in Louisiana, President Obama told the BBC the failure to pass gun-control laws in the United States is his biggest frustration.

President Obama: “If you ask me where has been the one area where I feel that I’ve been most frustrated and most stymied, it is the fact that the United States of America is the one advanced nation on Earth in which we do not have sufficient, commonsense gun-safety laws, even in the face of repeated mass killings. And, you know, if you look at the number of Americans killed since 9/11 by terrorism, it’s less than a hundred. If you look at the number that have been killed by gun violence, it’s in the tens of thousands.”
