Thats bad, first thing that came to my mind was. If you have a gate and they entered without your permission or a search order, it would be concidered tresspassing right? Cops cant just walk into someones property or into someones house as they like.
About the pitbull, haha it is a bit funny because if you have a large dog especially young ones that yet hasnt turned into their typical looks, they can be mistaken for a loooot of breeds, my Galahad has been a bloodhound, a st.bernard/blood hound mix and boxer lol. One cant but laugh, but I feel your anger, I would be furious if anyone just waltzed into my BY.
