The 36-year-old fighter was arrested 3 times over the years for getting violent with law enforcement officers -- including an incident where he grappled with FOUR cops who tried to arrest him at a restaurant.
Another time, Miller threw a ceramic tile at cops and threatened to attack them with a metal pole.
He was hit with a slew of charges for the incidents -- but Wednesday afternoon, he appeared in an Orange County, CA courtroom and plead guilty to 13 of 'em including:
- 2 counts of resisting arrest (felonies)
- 2 counts of assault with a weapon on a peace officer (felonies)
- 1 count of resisting an executive officer (felony)
- 3 counts of resisting a peace officer (misdemeanor)
- 1 count of false imprisonment (misdemeanor)
- 2 counts of vandalism (misdemeanor)
- 2 counts of battery (misdemeanor)
Miller was sentenced to 100 days in jail, but the judge gave him double credit for the 50 days he already served.
