The DOJ report [HERE] found from 2009 to 2010 (does not include Katrina info) all 27 incidents of NOPD deadly force were against African Americans, and in 2009  the department arrested 500 black and 8 white males under age of 17, which diverges "severely" from national data.

The report states "indeed, the limited arrest data that the Department collects points to racial disparities in arrests of whites and African Americans in virtually all categories, with particularly dramatic disparity for African-American youth under the age of 17. Arrest data provided by NOPD indicates that in 2009, the Department arrested 500 African-American males and eight white males under the age of 17 for serious offenses, which range from homicide to larceny over fifty dollars. During this same period the Department arrested 65 African-American females and one white female in this same age group. Adjusting for population, these figures mean that the ratio of arrest rates for both African-American males to white males, and African-American females to white females, was nearly 16 to 1.

Although a significant disparity in arrest rates for this age group exists nationwide, it is not nearly as extreme as the disparity found in New Orleans. Nationally in 2009, among those agencies reporting data, the arrest ratio of African-American youth to white youth, for the same offenses, was approximately 3 to 1. The level of disparity for youth in New Orleans is so severe and so divergent from nationally reported data that it cannot plausibly be attributed entirely to the underlying rates at which these youth commit crimes, and unquestionably warrants a searching review and a meaningful response from the Department.
