I've talked to investigators doing background checks on neighbors for various security clearances and I've never once let them in the house.
We do our talking on the front porch, or not at all.
And that's where I have absolutely no doubts about their sincerity, honesty or integrity.
In my case I let them in! I did not have anything to hide. I haven't been bothered since their third inquiry. Grassontop
Do you REALLY believe that?
