Yolo Co. (CA) Probation Department gets federal grant for pilot program

Flash incarceration is a way to hold probationers accountable for their actions without disrupting any progress they may have made, Gayton said. Instead of being locked up for a long stretch of time and likely losing their jobs or living situations—they serve a short sentence and can be subject to additional requirements by their probation officer.
Yolo County probation officials say that no one has refused a flash incarceration in the seven years since they implemented it.
With the pilot program, the probation office wants to introduce this practice to the mandatory supervision and felony populations.
