The main purpose of this legislation is to enhance the federal law regarding carjacking. It aims to make it easier to prosecute individuals who commit carjacking by clarifying the legal language and requirements involved in such cases. The key provisions of this law focus on two main changes to the existing carjacking statute. First, it changes the wording from requiring proof that the offender intended to cause death or serious bodily harm to simply showing that they acted knowingly. This makes it easier to establish intent in carjacking cases.
