Trade secrets, pah
The precise algorithms and weightings of parameters a trade secret?
If its not patentable, then its probably only secret because its obvious(ly flawed) and anyone with access to training data could have a go.
The authorities should own the process IP to ensure it has some level of transparency, even to themselves. Leaving decisions to a corporation (recalling OCP for example) is outsourcing law enforcement to an unacceptable degree in my view.
