However police agencies may choose to re-allocate their domestic abuse resource portfolio, the evidence-based model for testing innovations should be clear. There are both ethical and political reasons to introduce domestic abuse strategies with the same care as public health strategies. Both CARA and the Bracknell Forest ICMP were tested with as much rigour as testing a new pharmaceutical. If two English police agencies can do this, we suggest that others can follow their lead.
Whether the facts reported in these eight studies stand up to replication, however, remains to be seen. Thus, the most concrete answer to the question of “so what?” is that every police agency can now replicate these studies—with a clear precedent—to test their conclusions with local data. Once those findings are in hand in each police agency, there is every reason to take action based on these conclusions. The kind of evidence-based innovations this issue reports from Hampshire and Thames Valley provide strong examples of how policing can better reduce harm to victims of domestic abuse.
