Ridiculous! Kids getting into fights is nothing new, nothing to get so upset about, and definitely not an arrestable offense. I don't know who to fault most: the mother who called the cops or the cops for actually arresting the kid and holding him. I once saw a segment on COPS where they put a kid in handcuffs to scare him after he shoplifted, but they took the cuffs off after talking to him and released him into his dad's custody. That sort of thing I have no problem with. I probably wouldn't have had a problem if they had just handcuffed Isaac briefly, too. What was done here was beyond reason, however.

Full disclosure: I'm the son of an elementary school principal, so I'm a bit biased, but generally it's hard to blame school administrators for enforcing policies that are created at the school board level. I agree that zero tolerance is terrible--so, incidentally, do most school administrators. But it's a popular way to handle things politically, and until elected officials start to pay a price for enacting these policies, they'll keep doing it.
