In"withdrawal assistance type"telecommunication network fraud,the concept of"knowing"is different from that of conspiracy;it only requires a preliminary understanding that the assisted party is dealing with illicit funds."Prior collusion"is also different from joint conspiracy,as the mere intention to participate suffices.The completion of this crime is determined by the"control theory";generally,once the remittance is completed,the fraudster obtains control,except in cases where there is a 24-hour time lag during ATM operations.If the participation in the withdrawal assistance occurs before the crime is completed,it constitutes assistance;after completion,unless there was prior conspiracy,it should not be classified as joint crime,but rather as a crime of concealing or disguising criminal proceeds.
