Mandatory arrest

This article describes police policies in domestic violence situations:

Mandatory arrest first became the preferred policy in 1984 when Lawrence Sherman and Richard Berk published their landmark study of the relationship between arrest and recidivism in domestic violence criminal cases.

However, a July 2001 National Institute of Justice article says:

the published results from the five replication experiments produced inconsistent findings about whether arrest deters intimate partner violence.

This looks like another example where feminists have pushed through bad policy based on bogus research.
