In this case , I will state clearly that giving notes to other students will effect both sides , the one who receives and the one who gives . Then I will start  changing the way I teach this class in particular . I would give different assignments to each and every students to prevent the retired police officer to copy other students assignments . and I will state clearly that exams would depend on students understanding of the class and the class exams question\'s would not be multiple choice but essays which strongly depend on the student\'s understanding of the course . Then I will focus more on the retired police officer and made him contribute more in the class and gives him the impression of which he does not need to take notes from other students . I would appreciate him every time he contributes in the class discussion and I would ask him frequently to comment on his classmates answers and appreciate his comments , this way he would be more confident in both himself and his understanding of the course , and that would stope him from borrowing notes or coping answers , because now he is more confident on his own answers and his own understanding of the course and he does not need to borrow notes anymore .
