It gives much more power to the already very lenient judges. The RCCA allows for/changes:

• Penalties for many offenses significantly reduced, from robbery/burglary to carjacking and illegal possession of handgun. Even sexual assault and rape have been reduced.

• Bill removes mandatory minimums in the few categories that still hand them, allowing judges to continue issuing "slap-on-the-wrist" penalties, even for repeat offenders.

• The right to petition the judge to reduce a sentence has been expanded to all defendants. Currently it is limited to those who committed a crime before they turned 25. Many judges grant these petitions.

• Right to request a jury trial expanded to nearly all offenses. This will further overburden the already overburdened court system.

Among other changes allowing for repeat offenders to more easily continue availing themselves to the community. You can read the RCCA yourself if you have questions: https://legiscan.com/DC/text/B24-0416/id/2616873/Washington_D_C_-2021-B24-0416-Enrolled.pdf
