What is a loophole?
A loophole is different from a defence. Wikipedia defines a loophole as "an ambiguity or inadequacy in a system, such as a law or security, which can be used to circumvent or otherwise avoid the intent, implied or explicitly stated, of the system." The point of a loophole is to contravene the intent of a law, without technically breaking the law. Think of it as following the letter of the law, but not its spirit.
