In this paper, we develop our previous outline of a multi-agent architecture for regulated information exchange in crime investigations. Interactions about information exchange between agents (representing police officers) are further analysed as negotiation dialogues with embedded persuasion dialogues. An architecture is proposed consisting of two agents, a requesting agent and a responding agent, using a communication language and protocol with which they can interact in order to promote optimal information exchange while respecting the law. Furthermore, the agents' negotiation policies are defined and implemented and an implementation of the agent execution cycle is proposed, which will ultimately enable us to field test our model in order to supply a proof of concept.
