In the case of illegal drug trafficking, regarding whether to acknowledge the undertaking action of illegal drug trafficking when the person only have received the payment, however, have not yet possessed or obtained the drug, it is not appropriate to acknowledge starting to doing crime. Merely, the person received the payment according to the contract of sale, at least it is possible to acknowledge the undertaking action of drug trafficking crime. In other words, it is problematic that whether this level of action is preparation stage of crime or is relevant to attempting crime. If the person already signed the contract of sale, it can be seen as the direct action of configuration requirement not as the action of preparation stage. Regarding an indecent assault, if someone tried to hug the victim with the intention of harassment within the distance of 1m with the victim, even though there was no physical contact, this has proximity in time/place with actus reus of actual crime. Without the intermediate intervention action, it may be considered as action that is possible to directly fulfill actus reus. According to the crime plan of a person, he/she is about to hug and assault the victim. Action of raising hand to hug the victim is the last stage of actus reus which other intermediate intervention action is not needed. Therefore, attempted indecent assault is considerable.
