Kyle Rittenhouse's acquittal on murder charges on Friday opened yet another front in America's longstanding fight over gun rights: Is it acceptable for a teenager to bring an assault-style rifle to a protest?

Conservatives hailed Rittenhouse as a hero for exercising his right to self-defense when he fatally shot two demonstrators and wounded a third who he said attacked him last year at a racial justice protest in Kenosha, Wisconsin.

Gun control advocates warned the jury's verdict could inspire a new wave of armed vigilantism, after Rittenhouse traveled in August 2020 from his Illinois home to Kenosha after demonstrations erupted following the police shooting of a Black man, Jacob Blake.
