@Inductivist Okay. I can control for 5. I don't have variables for 3 (just population size). 1 is already controlled for in the sense that virtually all reports of force occurred during officer-initiated contact.
@Inductivist I can't control for 2 (there's one variable asking if reason for being stopped was DUI suspicion, but none that ask if respondent was actually under the influence)
@Inductivist You're right. Force is less likely to be used when it's a single officer relative to two or more. The inclusion of this variable further narrows the BW gap from (0.008->0.005) 
@Inductivist Of course, one might argue that the fact that more officers are called for black than white suspects = racism. But it's also very possible that black suspects are involved in more serious/violent crimes, which call for a larger police presence.
