*p < .01

**p< = .05; Full sample represents 847,928 census block group month-years for crime and 341,962 census block group month-years for arrest.

Note: All models include parameters for Impact Zone, probable cause (PC), and non-probable cause (NPC) stops. Robust standard errors are reported in parentheses.
