Does Newsweek understand the definition of plagiarism?
Nope.
These are journalists.
They are below the English language competency level of a third grader and they certainly do not know how to look up and understand the definition of plagiarism or any other term.
Students who cannot make it in any rigorous field of study but are semi-competent in some area of study generally end up in the teachers college.
The washouts from the teachers college land in the school of journalism where competency and intellect are not required.
