ubiq: The majority of states have adopted preferred arrest policies that require police to either arrest one or both parties at the scene, or to write a report justifying why an arrest is not made, and some states — including New York, Wisconsin, and Minnesota — went further and have even adopted mandatory arrest policies requiring that an officer make an arrest during a situation where the officers suspect domestic violence even if no one presses charges or even tells the officers there was no violence.
In states with mandatory arrest policies, police are encouraged not to leave the scene without making an arrest. This results in many innocent arrests and unwarranted court and civil and crimson authorities interfering in families lives.
