The reforms, which would go into effect in January 2023, will avoid the most dangerous pitfalls of quietly emerging “alternatives” to money bail: algorithms that predict peoples’ “risk” and detain those given higher scores, and surveillance devices that track people who maintain legal freedom before trial. These powerful tools are already used in a vast patchwork of jurisdictions across the country. Both are opaque and profitable and have gained prominence among bail reformers in places like California, where a failed effort to end money bail last autumn would have mandated prediction and increased surveillance. In California and elsewhere, reformers have maintained that algorithmic prediction and “electronic monitoring” constitute safe, effective, and just substitutions for money bail. Advocates and experts say the tools are just as racist and classist as the money-bail system. Now, advocates see Illinois’ victory as reason for cautious optimism about the future of pretrial justice in the state and even nationwide. The bill reduces the reach of the criminal legal system, advocates said. They look beyond the money-bail ban, to the legislation’s unprecedented restrictions on an emerging and largely hidden system of prediction and surveillance.
