Rand Paul has issued a statement in response to his firing from the Washington Times for plagiarism.
My opponents have recently leveled a serious and baseless charge of plagiarism in my speeches and writings.
Plagiarism is the "wrongful appropriation" and "purloining and publication" of another author's "language, thoughts, ideas, or expressions," and the representation of them as one's own original work. The idea remains problematic with unclear definitions and unclear rules. The modern concept of plagiarism as immoral and originality as an ideal emerged in Europe only in the 18th century, particularly with the Romantic movement.
Plagiarism is considered academic dishonesty and a breach of journalistic ethics. It is subject to sanctions like expulsion.
Plagiarism is not a crime per se but in academia and industry it is a serious ethical offense, and cases of plagiarism can constitute copyright infringement.
Also, free online tools are becoming available to help identify plagiarism, and there are a range of approaches that attempt to limit online copying, such as disabling right clicking and placing warning banners regarding copyrights on web pages. Instances of plagiarism that involve copyright violation may be addressed by the rightful content owners sending a DMCA removal notice to the offending site-owner, or to the ISP that is hosting the offending site.
