The distressingly-complete Panopticon that has been built over the past several decades [0] makes it really easy for them to get you when they know to search for you, specifically. History (both recent and not-so-recent) has shown that if they don't know who they're looking for, or don't even know that they should be looking for anyone, they're just godawful.
