A woman beats up another woman. This scene is shot and edited very artistically so all we get is suggestions of blows before a man wrestles the woman to the floor to calm her down. As a result, the scene isn't very violent visually.
A man is roughed up by a gangster in a dark alley. The scene is very brief and very dark so we only see silhouettes of what is happening.
A man invades a house and shoots 3 people to death. One death happens offscreen (we just hear the body falling) and the other two have some blood.
A man is wounded in a shootout and we later see the slightly bloody bullet wound. We later see him touch his side and there is blood on his hand.
A gangster is killed but how it happens is confusing due to the way the film is edited. We briefly see the body in shadow. No blood in this scene.
A scene with a lot of gunfire but nobody gets hit.
