Publicized incidences of civilians being shot by police have led to calls for police to wear body cameras to record their interactions with the public. Figure 3.16 shows clustered bar graphs of attitudes about body cameras among police and the general public. Panel A shows opinions about whether body cameras will affect the way the public interacts with the police, and panel B shows opinions about whether they will affect the way police officers interact with the public.

a. What are the two variables being shown in panel A? In panel B?

b. In panel A, what percentage of police officers think that body cameras would make the public more likely to cooperate? What percentage of the public agree with that statement?

c. In panel B, what percentage of police officers think that body cameras would make police officers more likely to act appropriately? What percentage of the public agrees with that statement?

d. Do we see a stronger relationship between whether someone is a member of the police and attitudes about body cameras in panel A or B?
