They were met by hatred and violence — and local police often refused to intervene. But the Riders' efforts transformed the civil rights movement. On May 14, 1961, the Greyhound bus was the first to arrive in Anniston, Alabama. There, an angry mob of about 200 white people surrounded the bus, causing the driver to continue past the bus station. The mob followed the bus in automobiles, and when the tires on the bus blew out, someone threw a bomb into the bus. The Freedom Riders escaped the bus as it burst into flames, only to be brutally beaten by members of the surrounding mob. The second bus, a Trailways vehicle, traveled to Birmingham, Alabama, that day, and those riders were also beaten by an angry white mob, many of whom brandished metal pipes. Birmingham Public Safety Commissioner Bull Connor stated that, although he knew the Freedom Riders were arriving and violence awaited them, he posted no police protection at the station because it was Mother's Day. The violence toward the Freedom Riders was not quelled; rather, the police abandoned the bus just before it arrived at the Montgomery, Alabama, terminal, where a white mob attacked the riders with baseball bats and clubs as they disembarked. Attorney General Kennedy sent 600 federal marshals to the city to stop the violence. The following night, civil rights leader Martin Luther King Jr. (1929-68) led a service at the First Baptist Church in Montgomery, which was attended by more than one thousand supporters of the Freedom Riders. A riot ensued outside the church, and King called Robert Kennedy to ask for protection. Kennedy summoned the federal marshals, who used teargas to disperse the white mob. Patterson declared martial law in the city and dispatched the National Guard to restore order. On May 24, 1961, a group of Freedom Riders departed Montgomery for Jackson, Mississippi. There, several hundred supporters greeted the riders. However, those who attempted to use the whites-only facilities were arrested for trespassing and taken to the maximum-security penitentiary in Parchman, Mississippi. During their hearings, the judge turned and looked at the wall rather than listen to the Freedom Riders' defense, just as had been the case when sit-in participants were arrested for protesting segregated lunch counters in Tennessee. He sentenced the riders to 30 days in jail.
