Ahh, our crazy language. Actually, it was for making a gun gesture with his hand:

A 5-year-old boy was suspended from school after making a gun gesture with his hand on the playground.

His father, David Hendrix, was furious when he found out his son was issued a suspension for the gesture.

Instead, the boy should have straightened out his middle-finger. That would have sent the proper message.

In any event, the father made a stink about it and the principal and school board backed down.
