Parents are laughing at the intolerance of the zero tolerance rules that have been instituted in so many public schools. Laughing, that is, unless it is their own sons who are victimized by policies that seem to lack common sense. It's a serious matter when a good child is expelled from school, suspended or sent to a detention facility to take classes with real delinquents. Here are some recent examples of how the zero tolerance hatchet is wielded in public schools.

A first-grader at Struthers Elementary School in Youngstown, Ohio, was suspended for 10 days for taking home a plastic knife from the school cafeteria in his book bag. The 6-year-old wasn't threatening anyone; he just wanted to show his mother he had learned how to spread butter on his bread.

A third-grader at O'Rourke Elementary School in Mobile, Ala., was given a five-day suspension for violating the substance abuse policy after classmates reported that he took a "purple pill." His offense was taking a multivitamin with his lunch.

At LaSalle Middle School in Greeley, Colo., three 13-year-old boys were given one-year suspensions because one of the students brought to school a key chain with a 2 1/2-inch laser pointer. The school called it a "firearm facsimile" and sent one of the boys, a good student who had never before been in trouble, to an alternative program where he is taking classes with young criminals and juvenile delinquents in "anger management," "conflict resolution" and gangs.

Four kindergartners at Wilson Elementary School in Sayreville, N.J., were suspended for three days for playing a make-believe game of cops and robbers during recess, using their fingers as guns. This case is now before the 3rd U.S. Circuit Court of Appeals.

When seven fourth-grade boys, who had never before been in trouble, at Dry Creek Elementary School in Colorado were discovered pointing "finger guns" at each other while playing a game of soldiers and aliens during recess, the principal found them in violation of the school's zero tolerance policy. After quizzing them about whether their parents owned guns, she required them to serve a one-week detention during lunchtime, sitting in the hall where they were teased and taunted by other students.

An 8-year-old at South Elementary school in Jonesboro, Ark., was punished with detention for pointing a chicken strip at another student in the cafeteria while saying "pow, pow, pow."

A 7-year-old at the Edgewood Independent School District in San Antonio, Texas, was banished for 11 days to an "alternative school" for troubled students when he was caught bringing a pocketknife to school. For three days, he was the only first-grader at the facility among older students guilty of serious offenses.

A 12-year-old at Magoffin Middle School in El Paso, Texas, stuck out his tongue at a girl who had declined his invitation to be his girlfriend. School administrators called this sexual harassment and suspended him for three days. Continued...
