Before going any further, let me make it clear that this article is not, in any way, condoning violence. (Sorry to disappoint you.) It won't talk about the neatest way to dispose of body parts, or help you figure out how to avoid jail time for opening up a can of whoop-a** on your neighbor.
However, after careful study, I've realized that what you need to promote your business effectively are the same things you need to commit the perfect murder. (Hypothetically, of course; remember, no humans were hurt in the creation of this article.)
