The resources of the justice system are often stacked against poor defendants. Matters only become worse when a person is represented by an ineffective, incompetent or overburdened defense lawyer. The failure of overworked lawyers to investigate, call witnesses or prepare for trial has led to the conviction of innocent people. When a defense lawyer doesn't do his or her job, the defendant suffers. Shrinking funding and access to resources for public defenders and court-appointed attorneys is only making the problem worse.
