Is There a “Jerk Exception” to the First Amendment?

Apparently so:

There was a justified outcry recently when a video surfaced … of an Ohio man William Bailey making fun of a young girl with cerebral palsy at a bus stop. It is a brief video but enough to enrage a nation. Now, Canton Municipal Judge John A. Poulos ordered the maximum sentence for Bailey, who pleaded no contest to reduced misdemeanor charges of disorderly conduct and aggravated menacing. I realize how emotionally charged this case has become, but should mocking be treated as a criminal act?

My own take on a different jerk-exception case here.
