Police in Wilmington, Delaware are investigating videos which show young children fighting in public while adults laughed and took cell phone video. 

One video shows two boys, believed to be between the ages of 4 and 7, repeatedly punching each other in the head.

Here's more from The News Journal:

In one video, two young shirtless boys, fought each other on a city sidewalk. In one clip, the taller child knocks the shorter boy to the ground. The boy then begins to cry. The 32-second clip then cuts to the two boys fighting near a porch, while a young girl tries to separate them.

A second video, that's 2 minutes and 27 seconds long, shows the shorter boy telling someone inside a parked minivan: "Get out. Get out."

The little girl gets out and goes after the boy with a shoe. She also tells the boy: "You're not getting in my mother's car anymore."
