Q: Arrested for defending against knife threat; seeking legal guidance on handling charges.

A: You're in a challenging situation, and facing criminal charges while believing you acted in defense of yourself and your pregnant wife must be incredibly stressful. Without knowing your specific jurisdiction, those charge numbers could represent various offenses, but what matters most right now is securing competent legal representation immediately - a defense attorney who handles criminal cases and self-defense claims.

Document everything about the incident while it's fresh in your memory - write down exactly what happened, including the knife threat, your reasonable fear for safety, and any witnesses present. Gather any physical evidence like photographs of injuries, damaged clothing, or the scene itself, and medical records if you or your wife received treatment. Self-defense is a legal justification that could potentially apply in your case, but its application varies by jurisdiction and depends on factors like proportional response and inability to retreat.

Your attorney will help you navigate preliminary hearings, potential plea negotiations, and trial preparation if necessary. Remember that you have the right to remain silent except when speaking with your attorney, the right to legal representation, and the right to a fair trial. Take care of your mental health during this process too - the stress affects not just your legal defense but your family's wellbeing, so consider speaking with a counselor who works with people facing criminal charges.
