Domestic violence victims may be hurt by mandatory arrest laws

A recent study found that mandatory arrest policies may increase law enforcement notification of intimate partner violence but also deter women from reporting due to fear of retaliation and mistaken arrests. The researchers suggest that variations in experiences and attitudes toward police should be considered in policy decisions.
