The Alabama County police sent out letters to parents suspected of not paying child support telling them they won tickets to the Auburn-Alabama game. All they had to do was show up with ID to collect. Instead of winning free tickets, they won an arrest. They called it "Operation Iron Snare" and it seems to have worked like a charm.
I really like how they had crappy pop music playing and balloons to really get these deadbeat parents' hopes up before they put the cuffs on them. They even went so far as to ask them which team they root for a few seconds before they break the news to them that they have a warrant for their arrest. What goes around comes around.
