What happens to Father at the end of Chapter 13?

In Chapter Thirteen, Leroy grabs Sam and rushes him away. Stick and Leroy get Sam into a car nearby and they leave the scene. Leroy puts the gun in the glove compartment. Sam is relieved that Stick is with him and notes that he'll let Stick figure out what to do next. There is a conversation about the whites who were present during the demonstration. Leroy says there are whites who were involved and seemed supportive "only as long as our freedom doesn't interfere with their superiority." Leroy says those people are hypocrites though they can't see it themselves and the blacks don't recognize it until there's some action that reveals it. There is some conversation about Sam becoming more involved in the Black Panthers but Stick intervenes, saying Sam is too young to understand the implications or to make his own decisions. Sam is furious that Stick would make the decision for him. They argue but Stick insists that Sam go home.

Sam arrives at home to find his mother seated in front of the television. She barely notices him until he speaks to her and then she reaches out and touches his cheek. She seems amazed that he's alive and Sam turns his attention to the television. He watches as his father begins to speak. Then someone walks up to Roland, the camera tilts and someone else screams, then Roland falls to the ground.
