For those too lazy to read:

Loli is a form of Japanese anime. It depicts underage cartoon characters in sexually explicit situations. The cartoons are focused on sexualized plots and characters.

Lolicon is anime that depicts underage girls. Loli involving underage boys is called shotacon.

Possessing child pornography is illegal in the United States. Under the PROTECT Act of 2003, any obscene images depicting a minor is considered child pornography. The act was passed in part to make virtual child pornography illegal, even though it did not depict an actual child.

Because lolicon depicts an identifiable minor engaged in sexually explicit situations, loli violates federal law in the United States. You can be arrested and charged with a crime if you possess lolicon in any form.
