Ben Heller of Bloomfield Hills, Mich, with his wife Gabby and their daughter Zoe, 13, speak with Park Ranger Eric Pominville on Monday about the quote on the Martin Luther King Jr. Memorial on the Mall. “I think if you’re going to quote somebody, you should quote them properly,” Mr. Heller said about the paraphrased line. “It is etched in stone, but it can be fixed?” (Eva Russo/Special to The Washington Times)
