It can happen in an instant, and for a variety of reasons. You may be having a discussion with your spouse or an ex, when a disagreement becomes heated. Tempers and voices may go up. Unfortunately, if anyone calls the police, whether it seems necessary or not, there is a significant likelihood that someone will go to jail. In fact, New Jersey law specifically states that police must arrest a suspect if the accuser shows any sign of injury, and may arrest a suspect even if there is no visible sign. Furthermore, when you go to court, you can expect to find the judge to by sympathetic to the accuser, unless you have compelling evidence to refute the claim. It is critical to have experienced legal counsel to protect your rights.
