The first book in Campbell's critically acclaimed trilogy saw him as the country's first law student to argue a case before his state supreme court. The second book witnessed him convict (and then free) an innocent man as a prosecutor in Washington, D.C. The current volume returns Campbell to the defense, tracks his transition to teaching in California, and culminates with his defending his wife and others in "California versus Drusilla Campbell." It was the largest mass-protest trial in San Diego history. Author's proceeds from the sale of TRIAL & ERROR Volumes I, II, & III will be donated to the Innocence Project at California Western School of Law, San Diego, California.
