Troy Aikman's Ex Wife Rhonda Tried To Use His Name To Prevent Arrest

It all went down when Rhonda was sitting in the back of the Murphy PD cop car ... after she was busted for allegedly being wasted in a high school parking lot.

As the camera in the squad car rolled, Rhonda begged for her freedom ... at one point telling the officer, "Do you know what this is gonna do to him? Troy?"

The officer replied, "I have no idea. You can have him call me."

Rhonda continued, "If you do this, it'll be on the TV and it'll hurt � it's gonna hurt Troy, it's gonna hurt me, is that what your goal is?"

"Is this really what you want to happen? To Troy? And me, and my kids? Is this what you want to happen? Or can you not just take me home?"

The officer shot down Rhonda's attempt ... and merely explained, "I'm just doing my job."
