How Old Do You Have to Be?

10-years-old seems fine. Boy stabs man who was attacking mother -- chicagotribune.com

Authorities say 38-year-old Daniel McCullough quarreled with the boy's mother over the weekend in the home the three shared in the South Side's West Pullman neighborhood.

The mother told McCullough to leave, but officers say he climbed back into the house through a back window and attacked the woman. They say the woman's son tried to intervene and when McCullough knocked him out of the way, the boy grabbed a kitchen knife and stabbed him in the left shoulder.

This kid deserves a commendation for quick thinking, and cool nerve under horrible circumstances.
