PHILADELPHIA—Protesters here march January 6 against the killing by cops of 20-year-old Bryan Jones. Police shot Jones three times in the head in the first few minutes of the new year. Five cops have been put on “administrative duty” while an investigation is held. In 2006 city police fatally shot 20 people, the highest number since 1980. On January 14, cops killed a second man and wounded a passerby in downtown Philadelphia.
