Which of the following should NOT be included in AM messages?

In the context of AM messages, which typically refer to communication in a law enforcement or emergency response setting, it is essential to convey information clearly and effectively. Special characters can create confusion or misinterpretation in the communication process. For instance, using symbols or characters not recognized by standard communication systems could result in messages not being understood or misinterpreted, which can hinder quick and accurate responses in critical situations.

In contrast, including the direction of travel, date and time of the crime, and NCIC abbreviations is important for the clarity and efficiency of communication. The direction of travel gives responders essential information to locate a suspect or vehicle, while the date and time of the crime provide context for the urgency and relevance of the information being transmitted. NCIC abbreviations facilitate communication by using standardized terms that are widely recognized in the law enforcement community, ensuring that messages are understood quickly and accurately.
