Human: What are the differences between state and federal laws? Assistant: 
The primary difference between state and federal laws is that federal laws apply to the entire United States while state laws only apply to the individual state. Federal laws are created and enforced by the federal government while state laws are created and enforced by the state government. Additionally, federal laws tend to involve matters that cross state lines such as immigration, interstate commerce, and taxes while state laws involve more localized matters such as crime and marriage. Lastly, violations of federal laws are typically punished more harshly than violations of state laws.
