MKB's linkblog points us to Infilitration, “the zine about going places you're not supposed to go.” It's full of advice. Consider this, from the infilspeak dictionary:

credibility prop n.

an item such as a clipboard or briefcase, carried or used by an infiltrator to reduce suspicion

As many people know, you can get away with a lot just by carrying a clipboard and looking like you know what you're doing.
