The Atlanta police officers involved in the violent arrest and tasing of 2 black college students who were in their vehicle during protests this weekend are now facing charges ... on the heels of 2 of them losing their jobs.

The Fulton County DA has charged 6 cops for using excessive force during the incident with Messiah Young and Taniyah Pilgrim Saturday night.

Four of the cops have been charged with aggravated assault -- Mark Gardner, for tasing Pilgrim; Ivory Streeter, for tasing Young and pointing a gun at him; Lonnie Hood for using a Taser on Pilgrim and Young; and Willie Sauls for pointing a Taser.

Another officer, Armond Jones, has been charged with aggravated battery for forcefully throwing Young down on the street and pointing a gun at him. The sixth officer, Roland Claud, is charged with criminal damage to property ... the couples' car.

Mayor Keisha Lance Bottoms fired both Gardner and Streeter almost immediately after learning of the incident, and the other 4 were placed on desk duty.

The students claim they were out getting food when they got caught in traffic and the chaos around them. They later spoke about the scary ordeal, saying they felt lucky to be alive ... and demanded change so similar incidents stop happening.
