I actually feel sorry for Detective Juli Gundermann, who sent out the letter. It's one thing to screw up. It's another to suddenly end up on probably every newspaper, TV spot and Congresscritter's attention in about, oh, 30 minutes. With thousands of very angry voters, backed up by multiple political organizations with lengthy experience of annoying and defeating much larger, better funded organizations. On a political hot potato item. That enjoys Constitutional protection.
Short of punting a newborn infant for a field goal at the Superbowl, I'm not thinking of a way to screw up worse. The Detective could have burned a few houses to the ground with tear gas grenades with the family pets inside and gotten off lighter, attention wise.
