"Since you have already known that these guys are all MLM members, why don't you arrest them at once?" Xiao Luo asked.
Qiu Yuanjie said with a wry smile, "It is true that MLM an illegal activity, but it is unique since the victims who had been indoctrinated do not realize that they are being cheated. Instead, they think that we prevent them from getting rich, so it is impossible to expect them to accuse the MLM members independently. The only way to implicate them is to catch them in the act and seize any compelling evidence we find.
"And the evidence you're referring to is the defrauding money?" Xiao Luo asked.
Qiu Yuanjie nodded and replied, "Right."
"But the gold star lecturer who is convincing them to invest is also your informer. Can't this sort of illicit money be used to charge them legally?" Xiao Luo said wonderingly.
