Last February, Emily Whittemore stepped onto the stage at Los Angeles’ Jumbo’s Clown Room in a pair of eight-inch Pleaser heels, a black string bikini, and an extra-large T-shirt with the face of Luigi Mangione printed across it. She writhed and wiggled on the iconic strip bar’s floor to System of a Down’s “Prison Song” as onlookers cheered, and eventually lifted the shirt up to her head and wrapped Mangione’s mug shot around her face.
