Most episodes contain violence. When people are shot blood sprays and splatters onto objects. The main theme is that a woman is shot by a mentally unstable man. There are bombing, graphic shootings throughout.
The most graphic episodes are those involving serail killers. As the crime scenes are shown in detail usually blood will cover the surrounding area.
The final episode is the most graphic as it starts with three men shown with their throats cut. Extremely graphic. Two are hung upside down and another is laid on the floor withasbestos forced into his mouth. The two who are hung upside down are bleeding profusley from the wound even though they are dead.
Later on there is a gun fight men in a car are shot with alot of blood spraying onto the windows. Another man is shot with blood.
Some mild beatings
A man is shot by a sniper, blood is seen.
Most of the violence is strong and brutal but there are some darkly comic overtones in the series as the characters react humourously to some situations.
