It's mostly a thought experiment but the general idea is to

- consider the actual effects on someone to be involved in a legal process; for lawyers it's just a workday but for people it's heavy to be accused of a crime and to wait for something awful (jail) to happen.

- define some time reasonable time constraints for everything, in order to give some incentives for the process to speed up. Prosecutors could be measured by how efficient cases go, and paying out some money could be an option.
