A six-year-old kindergartner was punished by school officials last week for ‘traumatizing’ students after pulling out a miniature rubber Lego gun – a toy just barely bigger than a quarter.

According to the boy’s mother, officials at Old Mill Pond Elementary School in Palmer, Massachusetts, grossly overreacted following the incident, which took place on a school bus Friday morning.

“She [driver] said he caused quite a disturbance on the bus and that the children were traumatized,” the boy’s mother Mieke Crane told the local station WGGB. “I could see if it was, you know, an Airsoft gun or some sort of pistol or live bullets or something. This is just a toy.”

School officials, who quickly sent letters home to parents explaining the situation, forced Crane’s son to write an apology letter to the bus driver and later gave him a detention. The boy who initially yelled about the gun was also asked to write a letter of apology.

“At 6 years old, I don’t really think he understood the zero tolerance policy and related it to this as the same,” Crane said.

Superintendent Thomas Charko attempted to downplay the situation, deflecting questions regarding the fiasco.

“There is no issue to comment about,” a spokesperson from Charko’s office said in response to a call from The Republican.
