Boy, church picnics have really changed since I was a kid. WPXI TV, Pittsburgh reports

About 100 teenagers swarmed from a McDonald's to Trader Joe's to a new Target store during a riot in East Liberty on Sunday, police said.

Police said the trouble started at Mellon Park, where Mount Ararat Baptist Church had just wrapped up its community picnic.

The Rev. Linda Oliver said that out of an estimated attendance of over 3,000 people, only a fraction of those people are responsible for starting the trouble.

The bonds of civilization are fraying.
