Krugman's Army Arms Up

For today's feature I could post about how the protesters in Madison got in trouble for, ahem, taking things into their own hands, but instead I will focus on the original protest.

Fights are erupting among Occupy Wall Street protesters, so much so that one corner of Zuccotti Park has emerged where protesters say they won't go for fear of their safety, the New York Daily News is reporting.

Police officers also have been warned of "dangerous instruments" being concealed in cardboard tubing, the News says it has been told by unidentified police sources.
