Why were charges against the Black Panthers dropped?

So apparently, even though the case was won AGAINST the Black Panthers, the charges were not only dropped, but the offending parties will be allowed to "poll watch" again at the same locations where they terrorized voters with paramilitary outfits, billy clubs and offensive name-calling.

Mr. Welch claimed one reason the charges against Mr. Jackson were dropped was that "he was a resident of the apartment building where the polling place was located," and thus allowed to be there. Mr. Wolf wrote back that Mr. Jackson "has never resided" at that address, which is a senior living facility called Guild House. At a fit and trim age 53, Mr. Jackson hardly qualifies for a retirement home.

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. How convenient.
