Sent 12: According to "The Path to Justice: A Five-Year Status Report on Access to Justice in California," prepared by the California Commission on Access to Justice, Katherine is just one of 4.6 million poor Californians whose basic civil legal needs -- often involving such critical needs as housing, health care, education, employment, safety and transportation -- are not being addressed.
Sent 13: California has a critical dearth of legal services for the poor, and, as this report makes clear, it is imperative that the state join with the federal government and private funders to increase resources so that all Californians, regardless of income, have equal access to our justice system.

Sent 16: California does have a strong network of legal aid organizations that try to help meet the needs of the poor, but there's just one legal aid lawyer available per 10,000 poor people.
Sent 17: We may promise "justice for all," but for those who can't afford a lawyer, that promise is often a lie.
