Which of the following traits is said to be found at all levels of policing?

Cynicism is recognized as a trait that can be found at all levels of policing due to the challenging nature of the job and the various experiences officers encounter throughout their careers. Police work often involves dealing with difficult situations, high-stress environments, and negative public perceptions, which can lead to a general feeling of disillusionment. This cynicism can manifest in different ways, including skepticism about the motives of others and distrust in the system they serve, and it transcends rank, affecting officers from entry-level positions to command staff.

In contrast, traits like anger, racism, and dogmatism may vary more significantly among individuals and may not be universally present across the entire policing spectrum. While they can certainly exist in some officers or departments, they are not inherent to the policing profession as a whole in the way that cynicism is. Thus, cynicism is a distinctive trait associated with the experiences and outlook of law enforcement personnel at every level, making it the correct answer in this context.
