It should be recognized that the participants in this study were 20 year old (approximately) college students and their tolerance toward swearing may be different than older people, or people from more conservative parts of our country. But the average age of criminal actors and victims is generally 17-24 years old. This is the group that law enforcement officers deal with the most. The implications of this research for police are that this group is not offended by swearing and may actually use profanity as a gauge of credibility. Officers should be must more careful and precise in noting statements taken at crime scenes, accident scenes and at dispute calls. Officers will want to be extra careful not to "sanitize" a victim's statement for a report. Officers conducting roadside interviews or station house interrogations can use this knowledge in helping to determine the sincerity of a suspect's statement; an officer may want to re-phrase a question (and dirty it up a little bit) in an effort to gain more credibility.
Whether on the side of a road or in the station house, law enforcement officers are always looking for the slightest edge in dealing with an unknown situation. An occasional swear word may not only relieve stress, but may actually lend credibility to what an officer says.
