Editor's note

Today an American actress marries into British royalty. With some 5,000 journalists attending, Meghan Markle and Prince Harry’s wedding is a global event. Small wonder, says Middlebury College’s Laurie Essig. Even though most Americans are not married they still pay attention to royal weddings. “Since the wedding of Queen Victoria to Prince Albert on Feb. 10, 1840,” she writes, “they’ve shaped the expectations Americans have about their own nuptials.”

This weekend is also, alas, a tragic one for Americans. Yesterday, another high school shooting - this time in Santa Fe, Texas - killed 10 people and wounded 10. And this is only three months after the even deadlier shooting at the Marjory Stoneman Douglas High School in Parkland, Florida. “We should not have this in common,” tweeted one of the teenage survivors of the Florida massacre. As the debate over what to do about gun violence hits the headlines once again, criminologist Frederic Lemieux disproves some of the common misconceptions about mass shootings.
