Every time we get the suspect's phone number, our team will use special WeChat to add the suspect. The picture is my ex-girlfriend. The point is to let me chat and tease the suspect every time. Be sure to feel welcome and rejection, and pretend to be busy but not busy! The most successful time: at about 12 in the evening, a criminal suspect was asked to take a taxi from another city 1 hour to the hotel where he was scheduled to meet, and the criminal suspect who was still excited was successfully arrested. Don't ask me why I'm so experienced, it's tears to talk too much. It seems that this is actually a means of arrest, which is much more efficient than three days and three nights. No fishing law enforcement.
