Characteristics of an "open-air" drug market include its accessibility to vehicular traffic, a large volume of non-drug abuser traffic, many escape routes for buyers and dealers, and general knowledge that crack can be bought or sold at the location. The average drug dealer in these markets is a male, 16 to 25 years old. Some of the most lucrative open-air drug markets are run by Jamaicans. When in the area of an open-air drug market, a uniformed patrol officer should assume a routine approach, entering the area at a moderate speed. Note the descriptions and operations of suspected dealers, and identify potential escape routes. If a decision is made to approach a suspect, it should be determined whether reasonable suspicion exists to conduct a search of the suspect's outer clothing and check for a stash of drugs that may be close at hand. If probable cause for a search is developed, a complete search should be performed. When time and personnel permit, a coordinated response should be mounted against such markets. The response should be under the control of one supervisor, and all communications should be channeled through that person. All members of the response team should be briefed on the assignment and their role in relationship to the tasks of other team members. Techniques for conducting area and vehicle searches are described. Test questions and answers on the material are provided.
