Yes, but not always. Usually, there is an evolution in the emails: the accused wishes to meet with the victim. As I said at the beginning, the objective here is to prevent the offence of sexual physical contact from happening. In the case of luring, the offence is committed even before there is physical contact. So you don't need proof that there was physical contact, but only proof that communication took place in order to sexually exploit the child.
