The less said about Palin pin the better; IMHO. This in itself could take on a 'life of it's own; and not a pretty one. (Why make a Sarah pin, any more of a hate target?)
First and foremost; these people were targeted; as Republican; and taunted/baited, as well, no doubt; as victim who was vulnerable/attractive and blond and with male companion - for these mindless perps; an additional adrenaline pumping challenge. That is enough story. (That said, think going from confusion in story to 'stolen Palin pins' a hasty leap of judgment!)
Jindal no doubt, IS left to diffuse rhetoric until coherent facts assembled. These venomous people are dangerous. No reason to give them more 'target' Sarah or otherwise - when being Republican is more than enough.
Some of the photos on that flickr site show the scuffle outside the restaurant. Odds are, the perps are in that crowd.
