Angelina Jolie Doesn't Want Brad Prosecuted

Angelina Jolie will not cooperate with law enforcement if there's a move to file child abuse charges against Brad Pitt ... TMZ has learned.

Our Angelina sources say she's adamant ... Brad should not face criminal charges for getting physical with 15-year-old Maddox on their private jet. We're told she'll go "radio silent" if authorities make a move to build a case against her estranged husband.

We're told Angelina was forthright with the L.A. County Dept. of Children and Family Services, telling social workers Brad struck Maddox (in the face).

Other sources say Brad did not strike his son in the face, but instead lunged at him and Angelina got in the way, causing Brad to inadvertently make contact with the boy's shoulders.

Angelina, we're told, has a singular focus ... protecting her kids, not punishing Brad.

DCFS does have the authority to recommend custody restrictions to the dependency court, although it's looking more and more like it will not reach that stage. Furthermore, given there were no injuries to Maddox and conflicting accounts of what happened, prosecution is also unlikely.
