Law students learn quickly that briefing cases is something you have to do for class, but when you need to actually understand the law, you put away your casebook and read your hornbook. For crimes, I recommend Understanding Criminal Law, by Joshua Dressler.
Criminal law is one of those subjects that doesn’t seem like it should be that complicated, but it is. This book was a great help to me in clarifying concepts like mens rea and inchoate crimes. You can click the cover image to use Amazon’s Look Inside feature and see what you think.
