The Oakland Police Department has produced a "by the numbers" summary of its activity during the November-December 2014 police brutality protests.
The document, to be presented to the Oakland City Council next week, says that the department responded to 24 protests, including one in Berkeley, in the final 38 days of the year. The demonstrations were touched off by a Missouri grand jury's decision not to indict a St. Louis-area police officer in the killing of 18-year-old Michael Brown.
The summary, embedded below, says a total of 9,860 protesters were involved in the events -- which doesn't mean 9,860 individuals, as it's likely that many participants took to the streets more than once during the last five weeks of 2014.
The report also gives details of the massive police presence during the demonstrations. It says the total number of officers involved in responding to the 23 protests in Oakland was about 6,500 -- 5,115 OPD personnel and 1,366 sworn officers from other departments who were responding to mutual aid requests. On average, that represents about two officers for every three demonstrators during the five weeks of protests.
Again, this doesn't mean the Oakland Police Department, which has a total strength of about 700 right now, put 5,000-plus individual officers on the street. That 5,115 number represents a lot of repeat appearances by Oakland officers assigned to protest duty. On average, each member of the department was involved in seven or so protests.
