A senior federal agent is assigned to coordinate a particular investigation in a local high-crime area infested with drug dealing. A possible "stash" house has been identified and there reason to believe drugs are being sold to between 30-40 different customers each day. Thus far it has proved impossible to introduce an undercover agent/officer to the dealer to make a buy. In addition, it has been determined that even if an agent could get inside it would be too dangerous to do so given this gangs predilection for violence. The chosen strategy is to set up surveillance on the location and observe the constant flow of persons in and out of the location. After several weeks of surveillance, it has been observed that approximately 30-40 vehicles drive to the location each night between the hours of 10:00pm and 5:00am.
