Alex Rackley was tortured and murdered by fellow Black Panthers in 1969 in New Haven, Connecticut. Rackley was suspected of being a police informant largely on the accusations of George Sams. Sams was a police informant but Rackley was not. The murder of Rackley may have been an attempt by Sams to divert suspicion away from himself. Rackley was interrogated and tortured for a week before being murdered.

Black Panther Party founder Bobby Seale was visiting New Haven at the time of the murder. Seale and thirteen other Black Panthers were arrested.

The trial of the Black Panthers became famous as the trial of the 'New Haven Nine.' Coming on the heels of the trial of the 'Chicago Seven,' in which Seale was also a defendant, for fomenting riots at the 1968 Democratic Party Convention in Chicago, some saw the trial as a concerted attempt to suppress political dissent in the US.

George Sams, Warren Kimbro and Lonnie McLucas were all convicted on various charges for the murder of Alex Rackley.

Bobby Seale and Erika Huggins were eventually acquitted by a hung jury. The jury voted 11 to 1 for Seale's acquittal and 10 to 2 for Huggin's acquittal.

What of Hillary Rodham and Bill Lann Lee? According to David Brock's unflattering biography, Hillary Rodham organized shifts of law students to monitor the trial of Seale and Huggins.

Bill Lann Lee was an undergraduate student at Yale and played no prominent role in the campus protests.

Did Bill Lann Lee and Hillary Rodham 'shut down' Yale with protests? No, sympathy for the Black Panthers was widespread on campus, both among the faculty and students. Yale President Kingman Brewster stated that he thought that the Black Panthers were unable to get a fair trial in the US. Yale University made concessions to the protestors and the demonstrations were largely peaceful, unlike the protests at Kent State University a few days later.

I can't find any other information on Erica Huggins so I can't confirm or disprove her involvment or subsequent accomplishments after the fact.

As much as I hate the Clintons, I can't honestly say that there is much validity in any any of these claims.
