California (and most every other state) already have laws that mandate "pro arrest" policies, but do not mandate the arrest itself. You have still failed to show that any funding program pays per arrest. Read the details of the funding and learn a little about the grant process.
The one you reference is number two on this list:

A full listing of funding opportunities (limited as they are) can be found here:

Creating programs, re-writing policies (something not mandated by all states, but mandated in CA), paying for vertical prosecution, counselors, resources, etc., are not the same as paying per arrest.
Most agencies in my state and the others do not receive any funding from these sources. Zero. Nada. Zip.
EDIT: Oh, and did you even READ the text of the grant that you tacked onto the now closed thread?

About the OVW Grants to Encourage Arrest Policies and Enforcement of Protection
Orders Program
The Grants to Encourage Arrest Policies and Enforcement of Protection Orders Program
(hereinafter referred to as the Arrest Program) recognizes that sexual assault, domestic
violence, dating violence, and stalking are crimes that require the criminal justice system to
hold offenders accountable for their actions through investigation, arrest, and prosecution of
violent offenders, and through close judicial scrutiny and management of offender behavior.
At each juncture in the criminal justice process, concerns for victim safety should guide the
actions of all partners in the system. Criminal justice agencies must collaborate among
themselves and in meaningful partnership with nonprofit, nongovernmental sexual assault and
domestic violence programs, including local shelters, rape crisis centers, victim service
organizations and sexual assault and domestic violence coalitions to ensure that victim safety is
a paramount consideration in the development of any strategy to address these crimes.
Additionally, representatives from criminal justice agencies working to prevent and reduce
sexual assault, domestic violence, dating violence, and stalking must have a clear
understanding of the roles of governmental and nongovernmental victim assistance programs.
This discretionary grant program is designed to encourage State, local, and Tribal governments
and State, local, and Tribal courts to treat sexual assault, domestic violence, dating violence,
and stalking as serious violations of criminal law requiring the coordinated involvement of the
entire criminal justice system. The Arrest program challenges the entire community to listen,
communicate, identify problems, and share ideas that will result in new responses to ensure
victim safety and offender accountability.
Note that it does not pay for each booking. It pays to create policies and programs to make victims safer. And no prevention program would be complete without consideration of the arrest and prosecution of offenders. So, of course, arrest policy is a component of any such comprehensive program.
