By itself, a Washington, D.C., jury’s acquittal of a 37-year-old man of assault for throwing a sandwich at a Customs and Border Protection officer isn’t particularly troubling; it’s actually a little funny. But placed into a larger pattern of D.C. jury behavior, it is the latest example of an increasingly partisan jury pool excusing Democrats for offenses that would almost certainly have sent a Republican to jail.

About 20 CBP officers were standing on 14th and U Streets, NW, a popular spot for drinking in D.C., on the night of Aug. 10, not bothering anyone. A man was so offended by the mere presence of immigration law enforcement officers that he started berating them with profanities, calling them “racists” and “fascists.”
