This bill amends the federal carjacking statute (18 U.S.C. 2119) to broaden the scope of the offense by altering the required mental state. It replaces the phrase "with the intent to cause death or serious bodily harm" with "knowingly" for the base carjacking offense, making it easier to prosecute. However, for cases where death results from the carjacking, the bill specifies that the motor vehicle must have been taken with the intent to cause death or serious bodily harm to trigger the most severe penalties, such as life imprisonment or the death penalty. This ensures a higher intent standard is maintained for the gravest outcomes.
