> Why would you take that risk when you know the system is being operated so that there is literally no difference between if you make the arrest or not?

The ability of police to forecast complex systems so accurately is astonishing.

The change being blamed for 2020/2021 elsewhere in this thread is "catch and release without cash bail." It's noted that there's been a 50% charge rate for a while on things as well. So if the police make that arrest, and that 50% charge rate held, half the time there's going to be a charge filed and regardless of if the person was held in jail or has to be brought back, that's still not "literally no difference."

Do people know Chesa is the DA for San Francisco, a 7x7 square mile city, only? You can't blame anything to do with the entire bay area on him.

Because they’re paid to and because, again, it is just not their job to evaluate or police based on how the rest of the justice system functions.
