I'd love for the scum to be reckless or bold, unabashedly or not. Alas, they usually try to keep low profile, lurk in the shadows. That's understandable, since the more active they are, the more mistakes they are bound to make. That's why I like to stir the pot a little. Even if they don't react and stay low - that's still a result, we can note who's been lurking. So either way, you're better be active.
