A couple of Maryland children have been suspended for using making hand gestures in the shape of a gun.

Earlier this month, six-year-old Rodney Lynch was suspended from his Montgomery County school after pretending to fire an imaginary gun.

The school reversed its decision after Lynch's parents appealed.

"They're saying he threatened a student, threatened to shoot a student. He was playing," said Lynch's father.

Some child psychologists say most 6-year-olds' minds aren't developed enough to understand why their idea of fun play might make adults upset.
