UFC star Jon Jones rounded up a crew and hit the streets Monday night -- swearing once again to protect the City of Albuquerque from violent looters and vandals ... and here's the video.
"I called upon some of the men of Albuquerque, New Mexico and quite a few showed up," Jones said in front of a group of 21 people.
Remember, Jones was out on Sunday night, too -- and forcibly snatched a spray can from a young man during the chaos on the streets.
So on Monday, Jones felt compelled to return to action -- and issued this warning to anyone looking to cause trouble in his city.
