The document discusses three main arguments about criminal law and justice:
1) Criminal sentencing laws like California's Three Strikes law have disproportionately impacted minority communities and have fallen short of their intended goals. These laws often result in extreme sentences that outweigh their effectiveness in reducing crime.
2) Social science research on issues like cross-racial eyewitness identification has helped inform criminal procedure and shed light on how race influences criminal trials.
3) Existing criminal procedure has created burdens for criminal defendants. Aggregation of discretionary decisions in the criminal justice system can lead to racial unfairness if not addressed. More analysis is needed on how race impacts criminal punishment and jurisprudence.
