Did I have a criminal in my garden???

One afternoon while I was at home with our 2 month old baby girl who was laying down on the floor in the living room. I heard a knock on the door. It was the police. Two police officers wanted to enter in my home as they said that we had someone they were looking for in our garden. Our garden had high fences around it so I was surprised and horrified that I could have a criminal in my backyard. The policemen also wanted to see if we were hiding someone in the house so they checked all the rooms and the garden. They only found a baby girl. I mean really... was I in some sort of a movie or candid camera!???
