DON'T JUST DO SOMETHING.

"I DON'T KNOW what the answer is," Kacey Musgraves shouted during her set at Lollapalooza on August 7, "but obviously something has to be fucking done." The country music star then led her fans in a chant that perfectly encapsulates the future of American politics: "Somebody fucking do something!" she screamed. "Somebody fucking do something!" the crowd screamed back.

Musgraves was, understandably, upset about the horrific back-to-back mass murders that took place the first weekend of August in El Paso and Dayton. She did not offer a specific something to be done. This may have been an attempt to appear nonpartisan, it may have been honest uncertainty, or it may just have been a sensible intuition that the middle of a music festival was not the right place to workshop public policy.

But the something matters an awful lot. In this case--and in so many others--"do something" actually means "do something to other people." It means "force other people to do something they don't want to do, even if you're not sure it will actually help." The call to "do something" privileges action over analysis and mandatory one-size-fits-all solutions over incremental, local, and voluntary action.

But in politics, that doesn't seem to count for much. Especially not when a bunch of politicians are in way over their heads, grappling with a highly flammable mix of genuinely troubling problems involving violence, racial hatred, inadequate health care, and terror.

"If we truly care about this," said President Barack Obama after a 2015 mass shooting in Colorado Springs, "if we're going to offer up our thoughts and prayers again, for God knows how many times, with a truly clean conscience, then we have to do something."

President Donald Trump has jumped onto the same bandwagon. Speaking to the press on the White House lawn before he departed to visit with victims of the August shootings, he too said he was prepared to "do something" about "any group of...
