In America if a person uses the ideas or words of others without mentioning the source then it is termed as Plagiarism. It is also academic crime in the American institutions where severe and sometimes very serious consequences are faced by those who practice this. The students are even expelled from the university. There are two types of plagiarism which are deliberate and accidental. In deliberate plagiarism the person copies the work of others intentionally whereas in accidental it happens by chance. Both are dangerous because one cannot tell “I did not know” when it comes to plagiarism. A plagiarist is an academic thief and when caught would face terrible consequences.
