Krasner acknowledged that other goals he hoped could accompany the policy have not yet been implemented. Washington, D.C., for example, has established a robust system for defendants to check in while awaiting trial, and Krasner said such appointments could be used to ensure that defendants take drug tests or meet with mental health counselors. It was not clear whether Philadelphia's court system could currently accommodate a similar system, and, if it can't, who would pay for the necessary changes.
