I read somewhere about a guy who did not select an ethnicity on his LSAC profile. He also listed his participation in several University groups and clubs that were typically predominantly african-american, some with "black" and "african-american" in the title, that he did legitimately join and participate in at least somewhat. The guy was caucasian, and I reckon that his intent was to dupe law school admissions committees into thinking that he was black. Would that increase your chances of admittance at many law schools, and would it be considered unethical to do if your not black or african-american. He did not technically do anything dishonest by joining extracurricular groups and not selecting an ethnicity on LSAC alone.
