Entering Chancery offices only requires a few items: a gas mask to ward off the inevitable manure odors, and a silver crucifix.
Won't hurt to have a nice S&W in the pocket, just in case.
Finding asses, bozos, pinkoleftyLiturgywonks, and various other social detritus in Chanceries is generally a higher-percentage game than in, say, a newspaper office. IOW, while both are target-rich environments, I think Chanceries are slightly MORE rich.
And I suspect that finding a jawbone or two which is available for the taking won't be that hard, either. I don't doubt for a minute that some employees actually died during their slumbers at those offices, allowing removal of a few jawbones without doing violence to the living.
