A school in Virginia
kicked
out a student for a year because he brought a leaf to school from
a Japanese maple tree. A school official thought it was marijuana.
The crucial point here is not that the official made a mistake, but
that once he knew it was a mistake, he still insisted on punishing the
child. This attitude towards mistakes characterizes the most cruel
and self-righteous officialdoms. We see it when people are convicted
of crimes and then proved innocent: the legal system resists
exonerating them. And now, under the guise of "zero tolerance", we
see it in schools.
Even if it had been fairly harmless marijuana — or even
some dangerous poison — that would be no reason to punish the
child for it in such a harsh way. A reprimand ought to be enough.
