Detective Roy Coleman of the Chicago Police Department is a close friend of Rally Vincent. The two often exchange tips and leads, and he occassionally helps smooth over legal difficutlies when Rally gets caught in a bind while on a job. He is an honest cop and while he may occassionally overlook a regulation or two for the bountyhunters of the Gunsmith Cats store, he would never consider breaking the law for them or anyone.
