scenario:
a high school student in san antonio, texas, who brought an unloaded handgun to school was charged with violating the gun-free school zones act of 1990. the student challenged the charge, claiming that congress did not have the power to override state law within public schools. in the 1995 case united v. lopez, the supreme court ruled that congress did not have the power to regulate public schools. instead, the court found that the power belonged to individual states.
