Possessing loli is illegal under federal law if two conditions are met. First, the anime depiction of an underage person is obscene or lacking serious value. Second, the anime was either transmitted through the mail, internet or common carrier; was transported across state lines; or there are indications that the possessor intends to distribute or sell it. Otherwise, simple possession of loli is not illegal under federal law. But if a person possesses a large amount of loli, prosecutors will likely infer that he/she intends to sell or distribute it. And unless the defendant created the loli images him/herself, prosecutors may have an easy time proving that the defendant received the loli over the internet or through the mail.
