Jerry Jackson, one of the Black Panther who intimidated voters during the last presidential election in Philadelphia (Berman Post: Black Panthers Intimidating Voters in Pennsylvania?), was a credentialed poll watcher for the Democrats. He was also a member of Philadelphia's 14th Ward Democratic Committee.
John Fund from the Wall Street Journal gives us a brief recap of the 'slam dunk' case that was dropped against these individuals including Jerry Jackson (Berman Post: Voter Intimidation Complaint Against Night Stick Wielding Black Panther Members Dismissed); "When none of the defendants filed any response to the complaint or appeared in federal district court in Philadelphia to answer the suit, it appeared almost certain Justice would have prevailed by default. Instead, the department in May suddenly allowed the party and two of the three defendants to walk away. Against the third defendant, Minister King Samir Shabazz, it sought only an injunction barring him from displaying a weapon within 100 feet of a Philadelphia polling place for the next three years—action that's already illegal under existing law. There was outrage over the decision among Congressional Republicans, the U.S. Commission on Civil Rights, and in the Justice Department's Civil Rights Division—especially after it was learned one of the defendants who walked was Jerry Jackson, a member of Philadelphia's 14th Ward Democratic Committee and a credentialed poll watcher for the Democratic Party last Election Day."

Within a week of the charges being dropped, Jerry Jackson was reinstated; "Mr. Jackson's MySpace page still lists one of his main 'general interests' as 'Killing Crakkkas.' Four days after the Justice Department dropped the complaint against Mr. Jackson, he again was named an official election poll watcher for the Democratic primary in Philadelphia's municipal election."
