I’M BEGINNING TO THINK THAT PUTTING YOUR KIDS IN PUBLIC SCHOOL IS PARENTAL MALPRACTICE: High-school freshman suspended for having a picture of a gun. Thoughtcrime! But wait, there’s more:

This incident is the latest in a growing line of extraordinarily strong reactions by school officials to things students have brought to school — or talked about bringing to school — that are not anything like real guns.

At D. Newlin Fell School in Philadelphia, school officials reportedly yelled at a student and then searched her in front of her class after she was found with a paper gun her grandfather had made for her. (RELATED: Paper gun causes panic)

In rural Pennsylvania, a kindergarten girl was suspended for making a “terroristic threat” after she told another girl that she planned to shoot her with a pink Hello Kitty toy gun that bombards targets with soapy bubbles.

At Roscoe R. Nix Elementary School in Maryland, a six-year-old boy was suspended for making the universal kid sign for a gun, pointing at another student and saying “pow.” That boy’s suspension was later lifted and his name cleared. (RELATED: Pow! You’re suspended, kid)

In Sumter, South Carolina, a six-year-old girl was expelled for bringing a clear plastic Airsoft gun that shoots plastic pellet to class for show-and-tell. The expulsion was later revoked.

Remember, these are the people who claim that they teach critical thinking.
