In the botched execution scene violence is actually quite tame, however it is still very disturbing. In this scene there is no visible blood.
Quite a few executions by electric chair. One is botched.
An inmate attempts to kill a prison guard by strangulation. He kicks other guards in the process. One guard intervenes before the inmate kills anyone.
A man spits a chewed up moon pie in another man's face and compares the results as that of blackface.
A man describes how his son was blinded in one eye after a dog attack. The injury is shown, but it has healed over and is not graphic. The man then talks about how he shot the dog as revenge for attacking his son.
Due to a purposefully botched setup, an inmate being executed in the electric chair is zapped for a long time. His body convulses, and flames erupt on his body and under his death hood as he screams. The scene lasts several minutes.
A man cradles the bodies of two dead girls, their hair matted with blood. Their father bloodlessly punches him across the face a few times before he is pulled away.
An antagonist is shot in the chest, some blood and bullet wounds appear on his shirt as he slumps down dead.
A prisoner elbows one guard and chokes another with handcuffs (a bit of blood spurts from his mouth) before bashing his head on the wall, a bit of blood is on their faces. He then kicks an incoming guard in the crotch before another one hits the prisoner twice, knocking him out.
We see a bit of blood on a door and a small blood trail on a floor.
An antagonist hits a prisoner once on the fingers with a billy club, it's later brought up that three of them were broken as a result.
A few punches and a slap or two from angry guards towards an antagonist.
