"In 2003 the United States spent a record $185 billion for police protection, corrections, and judicial and legal activities. Expenditures for operating the Nation's justice system increased from almost $36 billion in 1982 to over $185 billion in 2003, an increase of 418%.
"Local governments funded half of all justice system expenses. Another 33% of direct justice funding came from the States.
"Total justice expenditures comprised approximately 7.2% of all State and local public expenditures in 2003. Compared to justice expenditures, State and local governments continued to spend almost 4 times as much on education, twice as much on public welfare, and roughly an equal amount on hospitals and healthcare."
