Detectives more typically focus their energies on homicide and cases, as opposed to burglary and robbery cases, because:

A. there is political pressure to do so.
B. the victims can more often provide clues that make the cases easier to solve.

is it D

I agree.

To determine the correct answer, let's analyze the options:

A. there is political pressure to do so.
Political pressure can certainly influence law enforcement priorities, but it does not directly explain why detectives focus on homicide and cases over burglary and robbery cases.

B. the victims can more often provide clues that make the cases easier to solve.
This option suggests that victims of homicide and cases are more likely to provide valuable information or evidence that aids in solving the case. While this may be true to some extent, it does not fully explain why detectives prioritize these cases over others.

C. insurance companies can cover losses from theft but not the physical and emotional damage done by violent crime.
This option highlights the financial aspect of the crimes. Insurance companies typically cover losses from theft, but they cannot compensate victims for the physical and emotional damage caused by violent crimes. However, this reason does not directly address why detectives prioritize the solving of violent crimes.

D. police detectives place a higher priority on the solving of violent crimes.
This option suggests that detectives themselves prioritize the solving of violent crimes over property crimes such as burglary and robbery. Detectives often prioritize cases where there is an immediate threat to public safety or where the severity of the crime demands immediate attention. Therefore, this option is the most plausible explanation for why detectives focus on homicide and cases.

Based on the analysis, the correct answer is D.
