Answer:
Jails in Los Angeles are some of the most overcrowded in the state. This can lead to a wide variety of experiences if you are convicted. Some people are sentenced to 90 days and are out in 3 hours because of overcrowding. Others are sentenced to 5 days and serve all of them.
In order to give yourself the best chances of early release, factors like how your plea is worded and where you surrender are important. Counter-intuitively, sometimes applying for early release is the wrong strategy. The good news is that by being strategic, jail time can often be minimized or avoided.
