Propose a change to a current law. Pick a current law (state, municipal, or federal), explain the current law, and propose what and why you would change it. You might consider certain traffic laws, personal relationship laws, drug laws, age laws, restrictive laws, or any others that you find you disagree with. Research the laws on the internet. A good site for California laws is http://www.leginfo.ca.gov/.
The paper should summarize your findings, critique as needed, and most importantly, explain why you are interested in the topic and how you can apply the information to your own situation.
