Trevor's Tirade - Titles

Have you noticed that one absolute certainty of guilt these days - well if you're a man - is that the media and the authorities start calling you Mr.?  There is no better confirmation of guilt than to hear a sheriff or deputy refer to you as Mr. Summons.  With that title, the party is over.  Even OJ was referred to as Mr. Simpson!
Growing up as a child, one was always referred to by one's Christian name - that's first name for people living on the left hand side of the Atlantic.  To be called by one's honorific was something to strive for.  But then there was this weird American idea that if you called people by their Christian name everyone would get along better. Why?  There is nothing more annoying to me than to have some child come up to me and call me Trevor, when I haven't invited him to do so.  But maybe that's just me.  Nonetheless, if we can refer to criminals as Mr., why not the rest of us?  Surely a criminal on the run, like our local "hero" Dorner, loses any respect and should be referred to by only his surname. Come on People!
