The original question on the homicide survey in 1991, I believe, asked if a homicide was related to gang or organized crime activity. The answer we put, the choice for the police service, was simply yes, no, or unknown.
Since that time, in conversations with a lot of police forces, who are, of course, our respondents, it was determined that perhaps a better way to phrase that question--and we also changed this in our new crime survey for all crimes--would be to add the category of “suspected”. So we have “suspected” organized crime or gang activity; “yes”, which basically means confirmed, definite; and then “no”.
