Post-00S Work as Plainclothes, Wearing Cos to Catch Suspects

[Criminal investigation + fast pace + reasoning] Su Bai's first mission went a little off the rails. Others came to arrest suspects in plain clothes, but he wore pain clothes. "The most important thing about plainclothes is not to arouse the suspicion of the suspect." "Your master can't protect you this time." "I asked you to wear plain clothes, but I didn't ask you to wear this." Facing questioning from several veteran police officers. Su Bai didn't say anything. He was carrying a cartoon backpack and wearing pain clothes. He walked over and arrested the suspect who was eating melon. Seeing the suspect arrested, several veteran police officers were stunned. The suspect looked incredulous: I've doubted the restaurant owner, the waiter, and even the fried skewers across the street, but I haven't doubted you either!
