mass shootings getting deadlier

The mass shooting in Las Vegas on Sunday night was the worst in modern U.S. history. If it seems as though we only just experienced another deadliest mass shooting in modern U.S. history, it's because we did. About 16 months ago, Omar Mateen killed 49 people at an Orlando nightclub.
