“But that's a Lie!!” is a common refrain in my office. Unfortunately the officers who were called out to your incident are not there to judge truthfulness. They are dispatched to “protect and serve,” and most of the time that means they are charged with determining any alleged law breakers they encounter and then arresting them. “Let the Courts sort it out” is how officers are trained to deal with contentious factual issues.
The effects of a domestic violence arrest, wrongful OR justified, are life changing. Unlike many other types of charges I have handled, such as drugs, DUI, theft, etc, Domestic Violence Cases are “distasteful” for the general public. Most people can understand their friend that mistakenly drove drunk, shoplifted a trinket as a kid, has an addiction problem or even were involved in a violent fight at a bar.
