Admittedly, cops were in the wrong here: according to the law (which seems dumb), unicycles aren't considered transportation, so it's technically legal to ride them on the sidewalk (which is a terrifying thought for someone with dogs). But is this really worth $3 million of the city's and, by default, our tax money? Does (light) mockery constitute police brutality? I respect Mr. Peterson's right to redress police error, but $3 million just seems like rank opportunism.
Also, it should be illegal to ride a unicycle on the sidewalk (though Peterson recently got a ticket for "disorderly conduct" while unicycling on the sidewalk...).
