Adolescence. Will these dangerous teenage boys all end up in cells?

The new Private Eye is out now
A photo of the front cover of issue 1646 of Private Eye magazine. The headline reads "ADOLESCENCE" in bold red text, followed by a subheading: "A SHOCKING STORY OF TOXIC MASCULINITY, BULLYING AND ONLINE BRAINWASHING THAT LEADS TO TRAGEDY." The cover features three images of Donald Trump, J.D. Vance, and Elon Musk, each wearing MAGA hats, with their names captioned below. The bottom text asks, "WILL THESE DANGEROUS TEENAGE BOYS ALL END UP IN CELLS?", drawing a comparison between political figures and wayward adolescents.
