Dear Prudence,
My father has been a police officer for more than 30 years. Due to the recent violence (Aurora, Boston) he insists on carrying his gun on him at all times, including when he visits my home to see my small children. We live in a high-rise in a very nice neighborhood in a major city, but he reads the news about the violence in other parts of the city and won't leave his gun behind. This makes me extremely nervous. Recently at work, while cleaning his weapon, he had an accidental discharge. Luckily no one was hurt, yet he still carries his gun around my kids. I'm on the verge of banning him from being around my children. My mother and I have a difficult relationship and she thinks it’s fine he's packing 24/7. Am I overreacting?
