Protests have a funny way of kicking off when the mercury soars. The summer of 1967 is best known as “the summer of love”. It was a time when hippies flocked to America’s west coast to protest war, take drugs and peace out. But it was also a time when more than 150 race riots struck everywhere from Atlanta to Boston amid brutal temperatures, earning the period another name: “The long, hot summer.”
