While I see what you 2 are saying I cannot get on board with it to the degree you are saying. Suspicion alone is not enough for me to call the police, I need a little bit more confirmation than that.
True story,
When I was 19 my brother and his family lived across the street from me. They were supposed to be away at Christmas time (not the actual day) with my sister in laws family. My mom and sister looked out the window and saw his door opened and lights on and freaked out and called the cops. My dad, Brother in law and myself ran over thinking someone was robing the place. Turns out my brothers family decided not to stay because the accommodations were less than desired. The cops came and while everything turned out ok, we wasted police resources and what was nothing could have turned serious if just one of those responding cops were too amped up.
