Who came up with the summary, "spirals out of control"? Margaret, is, if anything, too much in control! One waits throughout the movie for her control to break. Who put her in charge of her son's destiny? Why is she willing, even at the moment she "speaks the truth" in all but this one respect, to specify HERSELF as the one responsible for her son's lover's death? She'll do anything to help him go on to college as a music major, but she won't be able to shield him always from the consequences of his own bad judgment. And perhaps her horrified expression as she watches the video reflects this realization as much as it does her visceral horror at the activity taking place. He is the one who is "spiraling out of control"--HER control. She is trying, presumably at her husband's behest before he shipped out, to make & keep the world safe for her family. But their domestic tranquility is built on a foundation of corruption--that of nearby Reno & its gambling enterprises & related criminal activities. Perhaps at the end when she breaks down & weeps, she is finally letting go of her "sense of control," along with her innocence, which has been compromised much more deeply than that of her son.
