Activists are disputing the police’s account of the arrests Wednesday outside the RNC after a protester attempted to burn an American flag. The police say they broke up the protest and arrested 18 people after the man holding the flag caught on fire. But activists say no one caught on fire, and this was only an excuse to make arrests. One of those arrested Wednesday at the protest was Gregory Lee “Joey” Johnson. He also burned a flag during a protest at the 1984 Republican National Convention in Dallas, Texas. That flag burning led to a 1989 Supreme Court case that set the precedent that flag burning is protected speech.
