Carson Beach Swim-In is held.

After a 300-car motorcade from Franklin Park, demonstrators protest the harassment of African-Americans two weeks earlier at Carson Beach. They are immediately confronted by a crowd of some 1,500 whites while some 800 Boston police attempt to keep order. Some 40 people are injured and 10 arrested during the ensuing violence on a Sunday afternoon at the same time that a “Southie Pride Day” picnic is being held at Marine Park a mile away in an effort to defuse the confrontation. A week of violent incidents across the city follow.
