What happened to innocent until proven guilty? Bail bond practices in New Orleans

New Orleans leads all US cities in jailing its citizens. Black people are jailed at a higher rate than people of other races. F. Daniels, Junior et al.  ask, “Why does the city — 300 years old, half of that post-emancipation — continue to extract the heavy human toll of conditioning freedom on the ability to pay the price set?” https://www.datacenterresearch.org/reports_analysis/from-bondage-to-bail-bonds-putting-a-price-on-freedom-in-new-orleans/ He suggests that the place to look for and answer is the “historical practice of exploitation of people of color, driven or sanctioned by the state,” that trades on the belief that blacks are dangerous and criminal. In reality, the bail bond practices in New Orleans are used to extract revenue and exert control. The people arrested in New Orleans are often poor and black. Black people are arrested at 2 ½ times the rate of white people. 84% of the $6.3 million paid in money bail is paid by black people. More than 500 people are in New Orleans jails at any given time for no reason other than they couldn’t pay for their release.
In Louisiana, judges are required to set a monetary bail for every charge the police officer cites when arresting a person. They cannot release people without their paying up front mail to purchase their freedom. Many incarcerated persons lacked the cash to pay their bail, and they are forced to see a bail bondsman. 3% of the 12% the bail bondsman charges is passed on to the court, the sheriff, the district attorney, and the public defender. Louisiana state law also states that Orleans Parish court receive of the aggregate bail amount. This raises a serious issue of financial conflict of interest. Can a court make appropriate decisions about defendants’ pretrial freedom when the court benefits from the payment of bond?
