Tim Lynch, the director of the Cato Institute's project on criminal justice, gave her 2016 book The War on Cops a negative review in Reason. Lynch concluded that "What Mac Donald calls a 'war on cops' is better described as a much-needed debate about crime, law enforcement tactics, and how to deal with systemic police misconduct," adding, "Conservatives have some worthwhile ideas to offer in this debate, but Mac Donald's polemics add heat, not light."
