No more pens in school?

It finally happened.
A school kid pulled a pen apart and made a "weapon" out of it using plastic balls from an airsoft gun.
Usually, straws and other tubes are used for spit wads but this kid obviously didn't want to be accused of trying to spread diseases.
Using the letter of the law as a weapon, the school administration claimed his pen body and pellets fell under the description of "projectile weapon" and had him charged with 3 misdemeanor assaults for shooting pellets at fellow students (who were apparently "annoyed").

Now they have to wrestle with the problem of any kid being able to convert a pen into a "weapon" at any time during the school day.
Maybe we should just ban pens; even in the administration areas.
