Your points are well taken and well understood. We just have a difference of opinion and that's fine. Since you challenged me to find one published incidence of a homeowner clearing his house, here's one.

As I stated in an earlier post, there are many more examples and they are easy to find. I just posted the first one I found. You may say that this example doesn't meet the strict definition of "clearing a house". I say that when a homeowner wakes up from a nap, arms himself and confronts multiple intruders, he has cleared his house. The news reports don't relate each minute detail of the incident, but I think this is sufficient to illustrate my point.
I don't mean to be argumentative. I'm just making the point that homeowners clear their own houses on a routine basis, notwithstanding the advice of the experts.
