In case of Marita, she search the books to write her paper and used three sentence of those. She thought that it will be OK if she wrote the referense. She did not knew that she was plagiarizing.

In Haley's case, however, she know that she was plagiarizing. She just draged and copied from the internet website. Even if she changed the sentences, 30% of her paper was not her own. She also knew that it was guilty when she was plagiarizing.

To compare two situation, Haley's case is obviously wrong but in Marita's case, it is not clear if she did wrong thing or not. For that reason, Haley could have serious punishment but for Marita's plagiarism, just warning to her will be enough.
