I find no flaw in this thinking. There are many things worth concealing which is no one's business. For instance we have some home inspectors who mistakenly use their E&O insurance as a marketing tool, If I had E&O no one would know but me.

Personally, I never let my left hand know what my right hand is doing, but I can imagine the hissy fit you would take if all of us Floridians who legally carry weapons were made to carry them exposed instead of concealed.

Wise people keep their own council, only fools announce to the world their intentions. Many home inspectors believe they are generalists and do not use their advanced training or experience as marketing tools because they are concerned that they will be held to a higher standard should something go wrong. The thing you and many others don't understand is that people are totally free to operate their business within the confines of the law anyway they see fit. Business life is about gaining an edge over your competition, those of still in business understand that concept.
