Rodney was just a corrupt dumb officer, I love how Joan catches him redhanded bashing Kath Maxwell, and front that point, he had to do all the corrupt dirty work Joan commanded him to do, like Bashing spider simpson (shocking), and picking up contraband with Kath to run her shop, and once even losing Merle, and while doing most the work, it was agreed he only recieve 10% of the cuts! (30% to Kath, and 40% to Joan)
