Wikipedia:Crime labels

A biography of a living person (BLP) often begins by applying a label to the person, single words or brief phrases used to identify that person. The choice of such labels should be made thoughtfully and based on support for the common use of that label in reliable sources (RS) and the nature of biographies in encyclopedias. In the case of living persons convicted of, or notable for, crimes, in particular, labels should be employed with caution.

The fact the label could accurately be used is not the crucial issue here. The crucial issue is Wikipedia policy surrounding original research, synthesis, undue weight, and particularly the interpretation of these policies when they interact with policy surrounding BLPs.

Much of the discussion here pertains to the use of labels in the lead of an article.
