More than five years have passed since the 2017 Las Vegas shooting, but Rep. Dina Titus (D-NV) still carries the memory of entering the police station in the middle of the night and witnessing the devastation.

Although the press release celebrated Nevada’s new gun safety laws, it also pointed out that in 2017 the state had the 14th highest gun death rate in the country and the third-highest crime gun export rate — guns sold in Nevada that are used for crimes in other states. It said that Nevada legislators could decrease those rates and continue strengthening gun laws by requiring a waiting period following all gun sales, as well as adding more restrictions for people accused of domestic violence from owning or possessing firearms.

Following the second anniversary of the mass shooting in Las Vegas, supporters of gun-control legislation are holding on to the slimmest of hopes for passing new laws, aiming to find a path forward in the face of a narrowing window for congressional action.
