They have high investigative abilities and have a track record of solving cases and cracking down on criminal organizations. On the other hand, they are known within the department as difficult individuals to manage due to their tendency to disregard work rules and procedures, make unilateral decisions, and their repeated problematic behavior. Although they are frequently cautioned and instructed by their superiors, their investigative achievements make it difficult to simply dismiss them.
