Something tells me we'll see a LSPD:FR mod sooner than we think. The Heists update essentially gave us everything we need, including a Police Station interior (unless that was already in the game), uniforms, and there's an abundance of different livery styles and sirens. Then there's the ambient events like muggings and robberies, car/bike jacking, etc. There's clearly enough to at least give us a very basic foundation of the mod, allowing third party modders to step in and help the team expand.
