Heather Mac Donald's book 'The War on Cops: How the New Attack on Law and Order Makes Everyone Less Safe' discusses crime statistics in Chicago, highlighting that Black individuals committed a disproportionately high percentage of homicides and juvenile arrests relative to their population share. The specific figures cited, 76% of homicides and 78% of juvenile arrests attributed to Black residents, with Whites committing 4% of homicides and 3.5% of juvenile arrests, and Hispanics making up about 30% of the population, are consistent with the narrative Mac Donald advances about crime demographics in certain U.S. Cities.

However, these statistics are drawn from specific datasets and time periods that may not reflect current or comprehensive trends. Crime data can vary year to year and depend on reporting methods, definitions, and law enforcement practices. Additionally, Mac Donald's work is known for its strong stance emphasizing law-and-order perspectives, which some critics argue may oversimplify complex social factors influencing crime rates.

In summary, while the numbers Heather Mac Donald presents are largely accurate for the period she analyzed, they represent one perspective on crime data that should be interpreted carefully alongside other sources and updated statistics.
