It is surely irresponsible to insert significant, fictitious incidents into movies marketed as true stories. Besides which, James Brown's life story was about as dramatic as they come. If you can't turn that into a compelling movie without inventing non-existent shotgun fire, nobody's life story is safe.
In the past decade, however, the number of uniformed police officers has remained more or less flat. Without a doubt, the most fiscally responsible way to increase the number of officers on our streets is to mobilize uniformed officers in administrative jobs and to use civilian employees to fill those jobs.
