According to South, some of the ethical problems with informants include all of the following except:

• A. Officers becoming personally involved with informants
• B. Overestimating the veracity of the informant's information
• C. Using coercion and intimidation to force the informant to cooperate
• D. Falsely complimenting the informant to make him feel essential to the operation

Answer: (B)

The main idea here is how officers’ conduct with informants can raise ethical problems. Ethical issues arise when interactions cross professional boundaries, exploit the informant, or undermine voluntary cooperation and the integrity of the investigation.

Officers getting personally involved with informants can blur professional boundaries and create conflicts of interest, leading to biased judgment or favoritism. Using coercion or intimidation to force cooperation violates the informant’s rights and corrupts the honesty and voluntariness of their help. Falsely complimenting the informant to make them feel essential to the operation fosters manipulation and dependency, which pressures the informant and can distort the information obtained.

Overestimating the veracity of an informant’s information, while dangerous and something to guard against, is not an ethical breach in the same sense. It’s more about reliability assessment and the need for corroboration and sound investigative procedures to avoid acting on faulty information.
