Two new stories of the damage done by dimwitted “zero-tolerance” policies: one about “weapons” [*](in this case a butter knife packed in a middle school girl’s lunch) and “drugs” [*] (asthma medication given by one student to another in a potentially life-threatening situation).
Zero tolerance is the bastard child of dim-wittedness out of litigiousness. It sounds good to concerned parents and voters, and it helps defend against charges that discretion has been abused for some discriminatory purpose by abolishing discretion altogether.
But as Madison said about liberty and faction, to try to prevent discrimination by abolishing discretion is like fighting fire by abolishing oxygen. Not a good deal.
