I'm not sure where I heard the following paraphrased quote, but I assume it's either from a movie or a comic book. It may not be from a reputable source like Gandhi or anything, but it's still fairly thoughtful.

The job of the police is to protect and serve the people. The job of the military is to combat enemies of the state. When the military takes the role of the police, the people become the enemy of the state.
