Here's the requested translation:
Seeing Wang Shoucheng kneel down, the riot police suddenly felt a sense of satisfaction, with many of them feeling immense relief.
This Wang Shoucheng, as the Deputy Secretary of the Political and Legal Affairs Committee, was responsible for supervising the Public Security Department. Though the Public Security System was under the committee's oversight, it wasn't directly managed by it. However, Wang Shoucheng was arrogant and domineering, treating these police officers as his personal enforcers, barking commands without regard for their dignity. Many harbored deep resentment towards him, yet they dared not provoke him.
Captain Qin felt similarly. He was usually an upright officer but powerless against Wang Shoucheng. Though he knew Xu Shanshan pointing the gun at Wang Shoucheng was inappropriate, he couldn't help but feel a sense of satisfaction. He also found himself inexplicably admiring Xu Shanshan, the beautiful young girl.
