Course Continuity
Students are encouraged to stay home if you are ill or experience flu-like symptoms. If you miss a class for any reason, it is still your responsibility to make up the work missed.

I offer the following to students who miss class due to illness:

- Class sessions are regularly recorded. If you are absent due to illness or some other unavoidable circumstance, email me and I can send you an email with instructions for accessing the recording for the class session(s) you missed.

- I will make PowerPoint slides or other class materials routinely available on the course site to everyone in the class.

- Please make an appointment to meet with me and I will review/answer questions about what you missed.

Should we hire more police or defund the police? Is it better to have a single criminal lawyer staff a case from start to finish, or to allow lawyers to specialize at particular stages? If we eliminate cash bail, will crime go up? Would shortening sentences save money or harm public safety?

Through their work in legislatures, bar associations, and the judiciary, lawyers frequently play a central role in determining how the criminal system is funded, structured, and operated. This seminar will teach students to marshal evidence about what does and does not work to build criminal justice systems that are more effective, fair, transparent, and humane.

The course begins with an introduction to the evidence-based paradigm, including questions of measurement, causal inference, heterogeneity, and generalizability. We will also explore critiques of, and limits to, the evidence-based approach. The bulk of the course will use guided, curated readings to examine real-world policy questions related to policing, prosecution, bail, plea bargaining, sentencing, corrections, and reentry. There will be a strong emphasis on primary sources, including research studies that establish what the evidence shows, as well as materials produced by legal professionals who use research to advocate for or against system reform.

Evaluation will be based on class participation, along with a final paper and presentation in which students propose a criminal justice system reform, present evidence as to why it will be effective, and defend their analysis.
