Maybe I just live in places where they're more common, but I'm pretty confused by this:

Police weren't laughing Monday over a supposed "senior prank" by a Peoria High School student they accused of showing up on campus wearing a ski mask.

Police were called and the school, 11200 N. 83rd Ave., was placed in lockdown for nearly 2 � hours as more than two dozen officers searched for intruder, fearing that the masked man possibly was armed.

The student, Zubair Hussaini, 18, was arrested in a nearby neighborhood after the masked man fled from the campus, said Mike Tellef, a Peoria police spokesman.

There's nothing to indicate he did more than a) wear a ski mask and b) was Arab. I don't think either of those things is a crime. Did he say something? Did someone else say they saw him with a gun? If they did and he didn't have one and didn't ask someone to say so to create the prank, they've arrested the wrong guy.) Or was he arrested for wearing a ski mask while Arab? I have to guess there's something to this story not reported.
